Abstract :

La0.9Sr0.1Ga0.8Mg0.2O3 (LSGM) with an extraordinary oxygen-ion conductivity has been extensively studied as an electrolyte material for intermediate temperature solid oxide cells (SOCs). However, the conventional hightemperature sintering process of electrodes results in detrimental reaction between LSGM and Ni-based hydrogen electrode and microstructural coarsening of the electrode. Herein, a buffer-layer-free LSGM electrolyte-supported single cell with a nanostructured Ni-Gd0.1Ce0.9O1.95 (GDC) electrode is developed using a sintering-free fabrication approach. The cell exhibits a peak power density of 1.23 W cm-2 at 800 degrees C and an electrolysis current density of 1.85 A cm-2 at 1.5 V with excellent operating stability. The good performance and durability is owing to the synergistic effects of the elimination of elemental interdiffusion at the electrode/ electrolyte interface, polarization induced in situ formation of hetero-interfaces between Ni-GDC and LSGM, and remarkable structural stability of Ni-GDC. This study provides an innovative means for the development of efficient and durable buffer-layer-free LSGM-supported SOCs.

Abstract :

Perovskite oxide Ba0.5Sr0.5Co0.8Fe0.2O3-delta (BSCF) is a highly active cathode material widely studied for intermediate temperature solid oxide fuel cells (IT-SOFCs), however, the tendency of phase transition of BSCF under IT-SOFC operating conditions poses a critical challenge for its reliable applications. Here, a multiphase BSCFGd0.1Ce0.9O1.95 (GDC) nanocomposite with heterogeneous interfaces is synthesized at a relatively low calcination temperature of 750 degrees C. Both the multiphase composition and microstructural morphology of the nanocomposite are very stable during annealing at 750 degrees C. The unique multiphase structure and ultrafine microstructure of the nanocomposite can be maintained in the resultant cathode through a sintering-free direct assembly fabrication method. As a consequence, a corresponding single cell based on the BSCF-GDC nanocomposite cathode generates a maximum power density of 1.41 W cm(-2) at 750 degrees C with outstanding galvanostatic stability for 100 h. This work provides an effective means for the design and utilization of highly active BSCF-based nanocomposite cathodes for durable IT-SOFCs.

Abstract :

Perovskite oxide La0.9Sr0.1Ga0.8Mg0.2O3 (LSGM) is an intermedium-temperature solid oxide cell electrolyte material with extraordinary oxygen-ion conductivity. However, the manufacturing procedures of LSGM discs are complex involving multiple steps of powder preparation, forming, and sintering at high temperatures. Herein, thin LSGM electrolyte discs are prepared by coupling of tape casting and in situ solid-state reaction using oxides/carbonates as the feedstock. A pure-phase LSGM electrolyte disc with uniform elemental distribution is obtained by sintering at 1450 degrees C, and it possesses an ionic conductivity of 0.105 S cm(1) at 800 degrees C, a thermal expansion coefficient of 12.2 x 10(6) K-1, and a bending strength of 156 MPa A 170 mu m thick LSGM electrolyte-supported single cell delivers a peak power density of 0.96 W cm(2) at 800 degrees C and an electrolysis current density of 1.82 A cm(2) at 1.5 V with no noticeable degradation for 200 h. The findings of this research provide a cost-effective approach for manufacturing the LSGM electrolytes of efficient and durable solid oxide cells.

Abstract :

A challenge hindering the development of durable solid oxide fuel cells (SOFCs) is the significant performance degradation of cathodes owing to poisoning by volatile Cr originating from the FeCr alloy interconnect. Herein, a heterogeneous catalyst coating, composed of Ba1-xCe0.8Gd0.2O3-delta and BaCO3, remarkably improves the oxygen adsorption, dissociation capability, and Cr resistance of a La0.6Sr0.4Co0.2Fe0.8O3-delta (LSCF) cathode is demonstrated. The coherent heterointerface interactions formed between the catalyst coating and LSCF result in varied levels of surface strain and electrostatic interactions, significantly suppressing Sr surface segregation on LSCF. A single cell with the catalyst coating-decorated LSCF (CC-LSCF) achieves a peak power density of 1.73 W cm-2 at 750 degrees C, with no noticeable performance degradation for 100 h. The CC-LSCF cathode also exhibits outstanding durability under accelerated Cr poisoning conditions, compared with the tremendous degradation rate of 0.42% h-1 for the bare LSCF cathode. The enhanced Cr resistance is attributed to synergy induced by the stabilization of the lattice Sr cations by heterointerface interactions and the remarkable structural stability of the catalyst coating under Cr poisoning conditions. The novel heterointerface engineering strategy in this study provides insight into the design and development of active and Cr-tolerant cathodes. A heterogeneous catalyst coating composed of Ba1-xCe0.8Gd0.2O3-delta and BaCO3 remarkably improves the oxygen adsorption, dissociation capability, and Cr tolerance of La0.6Sr0.4Co0.2Fe0.8O3-delta cathode. The enhanced Cr tolerance is attributed to synergy induced by the stabilization of the lattice Sr cations by heterointerface interactions and the remarkable structural stability of the catalyst coating under Cr poisoning conditions. image

Abstract :

Developing effective adsorbents for wastewater purification is crucial, as excessive emissions of toxic dyes and heavy metal ions have been proven harmful to ecosystems and human health. A NiFe-layered double hydroxide/ graphitic porous carbon (NiFe-LDH/GPC) composite was fabricated by introducing NiFe-LDH nanosheets into GPC via a simple hydrothermal method to utilize the advantages of both materials fully, and thus ultimately obtain a composite adsorbent with improved adsorption properties. The samples obtained were comprehensively characterized by various characterization means, and the effects of several critical influential factors on the pollutant uptake capability of the NiFe-LDH/GPC were also studied through batch experiments. The results show that the as-synthesized NiFe-LDH/GPC exhibits a three-dimensional (3D) fluffy ultrathin-wall hierarchical porous structure, which possesses a high specific surface area and pore volume separately up to 506.74 m2/g 2 /g and 0.22 cm3 3 g- 1 as well as a relatively narrow pore size distribution. These characteristics bring advantages to enhance the adsorption ability of the NiFe-LDH/GPC for cationic/anionic dyes and heavy metal ions such as congo red (CR), malachite green (MG) and hexavalent chrome (Cr(VI), which reached the maximum adsorption capacity of 1726.51 mg/g, 1157.11 mg/g and 155.72 mg/g under the optimum conditions, respectively. Meanwhile, the adsorption behavior can be well described by the pseudo-second-order kinetic model and Langmuir isotherm model, reflecting that the sorption process mainly occurred chemically in the adsorbent monolayer. Furthermore, the NiFe-LDH/GPC maintained relatively high adsorption performance after multicycle testing, manifesting its good recyclability and stability.

Abstract :

Rational construction of high-efficiency photoelectrodes with optimized carrier migration to the ideal active sites, is crucial for enhancing solar water oxidation. However, complexity in precisely modulating interface configuration and directional charge transfer pathways retards the design of robust and stable artificial photosystems. Herein, a straightforward yet effective strategy is developed for compact encapsulation of metal oxides (MOs) with an ultrathin non-conjugated polymer layer to modulate interfacial charge migration and separation. By periodically coating highly ordered TiO2 nanoarrays with oppositely charged polyelectrolyte of poly(dimethyl diallyl ammonium chloride) (PDDA), MOs/polymer composite photoanodes are readily fabricated under ambient conditions. It is verified that electrons photogenerated from the MOs substrate can be efficiently extracted by the ultrathin solid insulating PDDA layer, significantly boosting the carrier transport kinetics and enhancing charge separation of MOs, and thus triggering a remarkable enhancement in the solar water oxidation performance. The origins of the unexpected electron-withdrawing capability of such non-conjugated insulating polymer are unambiguously uncovered, and the scenario occurring at the interface of hybrid photoelectrodes is elucidated. The work would reinforce the fundamental understanding on the origins of generic charge transport capability of insulating polymer and benefit potential wide-spread utilization of insulating polymers as co-catalysts for solar energy conversion. Uniform non-conjugated insulating polymer encapsulation on the metal oxides remarkably enhances the spatially directional electron transport, wherein the ultrathin insulating polymer functions as an electron trap to facilitate the charge separation in solar water splitting. image

Abstract :

Ammonia (NH3) is an easy to store, zero-carbon emission hydrogen carrier. The current primary challenges in enhancing the yield and faradaic efficiency of the electrocatalytic nitrogen reduction reaction (NRR) for ammonia synthesis are widely recognized to be the inhibition of the competing hydrogen evolution reaction (HER) and the activation of N equivalent to N to facilitate its cleavage. Here we select perovskite oxide materials La0.6Sr0.4Co0.2Fe0.8+xO3-delta (LSCF0.8+x, x = 0-0.1) as the NRR electrode for the proton-conducting solid oxide electrolyzer cells (PCECs). We construct a more effective metal oxide interface via in situ exsolution of CoFe alloy nanoparticles (NPs), which promotes N equivalent to N activation and cleavage by applying a certain voltage at 500 degrees C, thereby accelerating the gradual synthesis of NH3 with proton H+. At 500 degrees C and 0.8 V, the maximum NH3 synthesis rate is 3.75 x 10(-9) mol s(-1) cm(-2) while the highest faradaic efficiency is 3.05%, and there is no damage to the microstructure after continuously working for 100 h, indicating that this material as the electrode is beneficial to the electrocatalytic synthesis of ammonia in PCECs.

Abstract :

Nanostructured air electrodes play a crucial role in improving the electrocatalytic activity of oxygen reduction and evolution reactions in solid oxide cells (SOCs). Herein, we report the fabrication of a nanostructured BaCoO3- decorated cation-deficient PrBa0.8Ca0.2Co2O5+delta (PBCC) air electrode via a combined modification and direct assembly approach. The modification approach endows the dual-phase air electrode with a large surface area and abundant oxygen vacancies. An intimate air electrode-electrolyte interface is in situ constructed with the formation of a catalytically active Co3O4 bridging layer via electrochemical polarization. The corresponding single cell exhibits a peak power density of 2.08 W cm-2, an electrolysis current density of 1.36 A cm-2 at 1.3 V, and a good operating stability at 750 degrees C for 100 h. This study provides insights into the rational design and facile utilization of an active and stable nanostructured air electrode of SOCs.

Abstract :

Degradation of cathodes caused by the gaseous Cr species from a Fe-Cr alloy interconnect is a key issue in the development of durable solid oxide fuel cells technologies. Herein, we explore the effect of infiltration of BaCO3 nanoparticles on the electrocatalytic performance and Cr-tolerance of La0.6Sr0.4Co0.2Fe0.8O3-delta (LSCF) cathodes. The BaCO3 increases the performance of LSCF and the single-cell delivers a peak power density of 1.30 W cm-2 at 800 degrees C. The BaCO3 gives rise to no Cr deposition and Sr segregation on LSCF after exposure in gaseous CrO3, while a BaCrO4 surface layer is deposited on the cathode in contact with a Fe-Cr alloy. The synergetic effects of BaCrO4 layer on mitigating the reaction between segregated Sr and Cr2O3 and the very slow kinetics of reaction between BaCO3 and CrO3 contribute to the exceptional Cr-tolerance of the BaCO3 infiltrated LSCF cathodes.

Abstract :

Nanofibers have great promise as a highly active air electrode for reversible solid oxide cells (ReSOCs); however, one thorny issue is how to adhesively stick nanofibers to electrolyte with no damage to the original morphology. Herein, PrBa0.8Ca0.2Co2O5+delta (PBCC) nanofibers are applied as an air electrode by a facile direct assembly approach that leads to the retention of most of the unique microstructure of nanofibers, and firm adhesion of the nanofiber electrode onto the electrolyte is achieved by applying electrochemical polarization. A single cell with the PBCC nanofiber air electrode exhibits excellent maximum power density (1.97 W cm-2), electrolysis performance (1.3 A cm-2 at 1.3 V), and operating stability at 750 degrees C for 200 h. These findings provide a facile means for the utilization of nanofiber electrodes for high-performance and durable ReSOCs.
