Abstract ：
Layered double hydroxides (LDHs) have long been a hot research topic in supercapacitors because of their abundant reaction sites. However, LDH nanosheets tend to easily stack together during the synthesis process. Therefore, in this paper, a simple and effective stirring aging method was used to grow ZIF-67 uniformly on the surface of Ni-Mn LDH. The strategy can fully utilize the high specific surface area of ZIF-67 to provide a large number of active sites for Ni-Mn LDHs, which results in a significant increase of the capacitance contribution. The core-shell structure NM LDHs@Z has significant redox peaks and the surface redox reaction. The capacitance contribution of NM LDHs@Z increase from 21.7 % to 91.4 %. But it does not belong battery-type supercapacitors from the CV curves. It is necessary to find out a better characterization parameter to estimate the type of battery or capacitor, instead of the CV and GCD curve shapes. The Ni-Mn LDHs@ZIF-67 composites can achieve a specific capacitance of 1340 F g- 1at a current density of 1 A g-1. As the specific current density is increased to 10 A g- 1, the capacity retention can reach about 75 %, which is superior to that of the Ni-Mn LDHs (60 %). The hybrid supercapacitor is composed of Ni-Mn LDHs@ZIF-67 composite as the cathode and activated carbon (AC) as the anode with a 128 F g- 1 specific capacitance at a 1 A g- 1 current density and a 45.8 Wh kg- 1 energy density at a 850 W kg- 1 power density. The Ni-Mn LDH@ZIF-67 composites has a potential application in hybrid supercapacitors.

Abstract ：
Protonic ceramic fuel cells (PCFCs) are promising for efficient, clean energy conversion at low to intermediate temperatures, but the widely used BaZr0.1Ce0.7Y0.1Yb0.1O3-delta (BZCYYb) electrolyte has poor chemical stability in humid environments. Herein, we show that under oxygen reduction reaction (ORR) conditions, water accumulates at the BaGd0.8La0.2Co2O6-delta (BGLC) cathode-BZCYYb electrolyte interface, causing selective loss of Ba cations and decomposition of BZCYYb electrolyte. The introduction of triply ion-electron conducting La2Ce2O7-delta (LCeO) into the BGLC cathode expands its active reaction area, accelerates ORR kinetics, and suppresses water accumulation at the cathode-electrolyte interface and electrolyte decomposition. A single cell with the BGLC-LCeO composite cathode achieves a peak power density of 1.07 W cm(-2) at 700 degrees C, with no profound degradation at 0.5 A cm(-2) over 100 h. These findings provide guidance for the development of high-performance, durable PCFCs.

Abstract ：
Direct ammonia solid oxide fuel cells (DA-SOFCs) offer a promising pathway for the efficient utilization of carbon-free ammonia fuel. However, the nitridation of nickel-based cermet anodes in ammonia causes rapid microstructural coarsening, leading to durability problems. Herein, an efficient, ammonia-tolerant Fe-modified Ni-Gd0.1Ce0.9O1.95 (NiFe-GDC) nanocomposite anode is developed by coupling a self-assembly synthesis process with a sintering-free electrode fabrication technique. The as-synthesized nanocomposite oxides self-assemble into multiple phases, with GDC firmly grown on preformed NiO and NiFe2O4 nanoparticles, which are subsequently in situ alloyed in a reducing atmosphere to form a unique NiFe@GDC encapsulation structure with strong metal-oxide interactions. This NiFe-GDC nanocomposite not only provides abundant active sites for ammonia decomposition and electrochemical oxidation, but also exhibits exceptional resistance to nitridation and microstructural coarsening. Density functional theory calculations reveal that in situ-formed NiFe alloy lowers the energy barriers for ammonia adsorption and dehydrogenation while enhancing the nitrogen desorption process. An electrolyte-supported DA-SOFC with the NiFe-GDC nanocomposite anode achieves a peak power density of 0.61 W cm(-2) at 800 degrees C and exhibits outstanding operational stability for 100 h. This work offers new insights into the development of active and durable nickel-based nanocomposite anodes for DA-SOFCs.

Abstract ：
Three-dimensional (3D) nanoporous metals are being increasingly utilized in various fields such as catalysis, energy storage, and sensing. However, the conventional fabrication approaches for 3D nanoporous metals, such as dealloying and template methods, require additional sacrificial materials and multiple fabrication steps and generate chemical waste. Herein, we propose a novel gaseous (O2 and H2) oxidation-reduction (GOR) method to directly transform various transition metals/alloys into 3D micron/nanoporous materials by utilizing the spontaneous reconstruction of metallic atoms. This method eliminates the need for sacrificial materials and acidic/alkaline solutions, making it facile, cost-effective, and environmentally friendly. The resulting micron/nanoporous Ni/Ni alloy exhibits excellent mechanical properties, atomic hydrogen adsorption capability, and hydrophilicity, leading to outstanding electrocatalytic activity and durability for hydrogen evolution reaction. © 2024 Elsevier B.V.

Abstract ：
Transition metal sulfides are used in the field of supercapacitors due to their remarkable electrical conductivity and superior energy density. However, few research has been conducted on how the sulfidation process affects the structure and electrochemical properties of electrodes. The nanoneedle array Zn-Mn-Co sulfide (ZMC-S/NF) electrode is prepared by directly growing on nickel foam (NF) via a two-step hydrothermal technique. During the first step, the Zn-Mn-Co carbonate hydroxide nanoneedle skeleton can be obtained. During the second step, the nanoneedle skeletons are etched, and rough nanoneedle arrays are created by the introduced sulfur ions,i.e., the sulfidation process. The ZMC-S/NF electrode exhibits a specific capacity of 1401.0 C g−1 at 2 A g−1. It still has excellent rate performance with a specific capacity of 1015.3 C g−1 at 20 A g−1. Moreover, it exhibits excellent cycling stability with 81.9% capacity retention after 10,000 cycles. ZMC-S/NF as the cathode and activated carbon (AC) as the anode are assembled to be a hybrid supercapacitor (HSC), which has an energy density of 43.4 Wh kg−1 at a power density of 700.4 W kg−1. The effect of adding Zn and Mn to the Co3S4 on energy band structure and density of states during the sulfidation process is calculated by the DFT. The HSC devices constructed by two series-connected ZMC-S/NF//AC can light a star made by ten 1.8 V-red Light Emitting Diodes (LEDs) for 10 minutes. © 2024

Abstract ：
Protonic ceramic fuel cells (PCFCs) are characterized by a low activation energy for proton conduction and a high fuel utilization efficiency at low -to -intermediate temperatures. However, the sluggish oxygen reduction reaction kinetics on the cathodes drastically limit the power output performance of PCFCs. Herein, multiphase Gd 0.1 Ce 0.9 O 1.95 - BaGd 0.8 La 0.2 Co 2 O 6- delta (GDC-BGLC) nanocomposite cathodes are prepared by coupling selfassembly and sintering -free electrode construction methods. The nanocomposite cathode comprises mixed H + /e - conducting BGLC and O 2- conducting GDC and BaCoO 3 nanoparticles, and these phases are homogeneously mixed with coherent heterointerfaces. The nanocomposite cathode exhibits a significant increase in surface oxygen vacancies and three-phase boundaries, enhanced catalytic activity, and reduced activation energy for the oxygen reduction and water formation reactions. The results imply that the oxygen reduction and water formation reactions on the multiphase GDC-BGLC nanocomposite electrodes are most likely the dissociation, reduction and diffusion of oxygen species, which in turn is affected by the water vapor formed. An anodesupported single cell with the GDC-BGLC cathode exhibits a peak power density of 810 mW cm -2 at 700 degrees C with excellent operating stability at 650 degrees C for 110 h. This study provides a new strategy for the preparation of a high-performance and durable nanocomposite cathode for PCFCs.

Abstract ：
In the development of nanoscale oxygen electrodes of high-temperature solid oxide cells (SOCs), the interface formed between the nanoelectrode particles and the electrolyte or electrolyte scaffolds is the most critical. In this work, a new synthesis technique for the fabrication of nanostructured electrodes via in situ electrochemical polarization treatment is reported. The lanthanum strontium cobalt ferrite (LSCF) precursor solution is infiltrated into a gadolinia-doped ceria (GDC) scaffold presintered on a yttria-stabilized zirconia (YSZ) electrolyte, followed by in situ polarization current treatment at SOC operation temperatures. Electrode ohmic and polarization resistances decrease with an increase in the polarization current treatment. Detailed microstructure analysis indicates the formation of a convex-shaped interface between the LSCF nanoparticles (NPs) and the GDC scaffold, very different from the flat contact between LSCF and GDC observed after heating at 800 degrees C with no polarization current treatment. The embedded LSCF NPs on the GDC scaffold contribute to the superior stability under both fuel cell and electrolysis operation conditions at 750 degrees C and a high peak power density of 1.58 W cm(-2) at 750 degrees C. This work highlights a novel and facile route to in situ construct a stable and high-performing nanostructured electrode for 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.
