Abstract ：
Among many ways that can improve the electrolysis catalysts of seawater, designing the catalyst with hierarchical nanostructure has received extensive attention because it allows a larger surface area and more active sites. In this work, the NC-enveloped CoS/NiS@Cu2S catalyst with multi-level structure was successfully synthesized by using the complex of trithiocyanuric acid and copper as the metal dopant to coat the spherical Co-Ni precursor, and then by a straightforward one-step high-temperature self-vulcanization reaction. Trithiocyanuric acid not only facilitated the sulfurization of metal elements but also served as N and C source coated on the catalyst. This method constructed structure-controllable, multi-level, and yolk-shelled nanostructure in a facile manner, greatly increasing specific surface area, expanded mass transport channels, and enhancing the exposure of active sites. Besides, the coating of N and C elements significantly increased the electrical conductivity and electrochemical activity of the catalyst. As a result, CoS/NiS@Cu2S@NC exhibited excellent hydrogen evolution performance with the small overpotential of 105, 161, and 176 mV at 10 mA cm-2 in alkaline water, simulated alkaline seawater, and alkaline seawater, respectively. The present approach is proposed as an inspirational idea of the design of cobalt-nickel-copper-based multi-level structural nanomaterials as non-platinum electrocatalysts for hydrogen evolution in seawater.

Abstract ：
Hydrophilic macroporous sponge has been widely used in solar steam generation, catalysis, biosensing and other fields due to its high water transporting and adsorption ability. However, the synthesis step of hydrophilic sponge usually needs the assistance of a freezing process and toxic chemicals such as chemical crosslinkers or foaming agents. To solve these problems, herein, a novel and facile tactic based on the salting out effect was proposed to prepare hydrophilic amphibious open-cell macroporous sponge from the poly(vinyl alcohol) (PVA) solution. Glycerol, CaCl2 and Na3Cit were successively added into PVA solution. The sol-gel transition would occur due to the salting-out effect of Na3Cit and hydrogen bond crosslinking of glycerol. Finally, the hydrophilic PVA sponge with different shapes and sizes could be easily prepared. Moreover, this hydrophilic wet sponge could be room temperature dried into dry sponge and this dry sponge could be quickly restored to wet sponge after immersing in water due to its ultra-rapid water absorption. The microstructure and mechanical properties of PVA wet and dry sponges were studied. The PVA wet sponge showed excellent mechanical properties with a tensile strength, Young's modulus, and fracture energy of 1.51 ± 0.01 MPa, 0.44 ± 0.02 MPa, and 113.2 ± 1.6 kJ m−2, respectively. The wet sponge prepared in this work has an average porosity of up to 50 μm, and the pore structure can still be maintained during the conventional room temperature drying process. Moreover, the PVA sponge showed high stability in various aqueous media including acid, alkaline, and salt solutions. This work provided a simple and large-scale method to prepare amphibious open-cell hydrophilic PVA sponge. © 2024 The Royal Society of Chemistry.

Abstract ：
The in-situ polymerization of 1,3-dioxolane (PDOL) in battery cells has attracted extensive attention, however, the differences of Lewis acid initiators on the DOL monomer conversion (C%) and electrochemical properties has been ignored. Here, it is demonstrated that compare with Sn(OTf)2 Lewis acid initiator, the gelation of DOL is achieved at the lower addition of In(OTf)3. By optimizing their content in the gelation process, their C% are comparable which are 95.7 % and 93.5 % for In(OTf)3 and Sn(OTf)2, respectively. However, the higher ionic conductivity (7.1 × 10−4 S cm−1 at room temperature), electrochemical window (~4.5 V) and Li+ transference number (0.42) are obtained for DOL initiated with In(OTf)3, due to its lower molecular weight which is helpful to the intermolecular Li+ transport along PDOL main chain; In addition, the Li/Li symmetrical cell of In(OTf)3 can be stably cycled for >500 h at 3 mA cm−2, with an over-potential of 178mv. The storage and cycling impedances of half cells further proves the stable interface of In(OTf)3 initiated DOL toward to lithium metal in comparison with those of Sn(OTf)2. Scanning electron microscopy results show a denser and thinner interface in the DOL catalyzed by In(OTf)3. Finally, the assembled Li/LiFePO4 battery delivers specific discharge capacity and capacity retention rates of 115.5mAh g−1 and 85 %, respectively after 300 cycles at 1C. Through the initiator selection, the DOL synthesis and electrochemical properties can be tuned, which further broadens the design idea of PDOL based solid polymer electrolyte. © 2024

Abstract ：
Transition metal selenide composites with a core-shell structure offer a compelling alternative to platinum-based catalysts due to their large specific surface area, abundant edge sites, and exceptional synergy between the core and shell components. Core-shell selenide microspheres were prepared using bismuth bromide oxide (BiOBr) as the core and covered with a Ni–Co layered double hydroxides (LDH) shell transferred from ZIF-67 through a simple capping process. After selenization, this formed core-shell structure has an inner core of Bi2Se3 supporting a NiSe2/CoSe2 shell (denoted as Bi2Se3@CoSe2/NiSe2). The remarkable ability of Bi2Se3@NiSe2/CoSe2 to efficiently transfer electrons for iodide and H+ allows it to achieve exceptional photovoltaic conversion efficiency as a counter electrode (CE) in dye-sensitized solar cells (DSSCs) and demonstrate strong performance in the hydrogen evolution reactions (HERs). The power conversion efficiency (PCE) of Bi2Se3@NiSe2/CoSe2 electrocatalysts in DSSCs is 9.39%, significantly higher than that of Pt (6.89%). Besides, during alkaline HER (1.0 M KOH), Bi2Se3@CoSe2/NiSe2 has a lower onset potential of 35.5 mV and a smaller Tafel slope of 58.9 mV dec−1. This work provides a new approach to the design of cost-effective and efficient core-shell micromaterials, which can be applied to the synthesis of other Pt-free electrocatalysts. © 2024 Hydrogen Energy Publications LLC

At present, the exploration of renewable energy is a huge challenge, and water electrolysis is regarded as a promising method for producing hydrogen. However, the hydrogen evolution reaction (HER) has been hampered due to expensive Pt-based catalysts. Herein, the Fe2P-coated Ni2P/Co2P nanospheres with yolk-shelled structure were successfully synthesized according to a facile approach of doping transition metal elements and phosphating on the template Ni-Co nanospheres, successively. All samples were tested as HER catalysts at various pH environments. The results showed that the Fe2P-Ni2P/Co2P possesses superior electrocatalytic ability and good stability. The Fe2P-Ni2P/Co2P achieved the lower ηonset (overpotential at 1.0 mA cm−2) of 36.6, 64.2, and 65.9 mV, η10 (overpotential at 10 mA cm−2) of 89.7, 125, and 212 mV, and Tafel slopes of 48.0, 60.3, and 135 mV dec−1 in acidic, alkaline, and neutral solutions, respectively, exhibiting an excellent electrocatalytic activity of the multicomponent phosphides for HER. © 2024 Hydrogen Energy Publications LLC

Abstract ：
An available approach to ameliorate the property of electrocatalysts for transition metal selenides (TMSs) is to transform their structure, morphology, and elemental composition, especially for hydrogen evolution reactions (HER), which can be a long-term task. In this work, Ni-Co nanospheres were synthesized by a hydrothermal method, and then in the synchronous processes of selenization and carbonization, it reacted with the peripherally coated melamine-copper complex, which was the reactant between melamine and copper ions. Ultimately, CoSe2/NiSe2@Cu2Se-NC nanospheres with a core-shell structure were synthesized after annealing process. This special structure provided more active attachment sites, enabling CoSe2/NiSe2@Cu2Se-NC to exhibit excellent HER properties under wide-pH range. Especially, in acidic conditions, it had a low initial potential of 41.0 mV, a small Tafel slope value of 48.7 mV dec–1, and a long service life. The proposed scheme indicates that a new approach will be added to the synthesis of electrocatalysts based on TMSs. © 2024 Elsevier B.V.

Abstract ：
Among the various non-precious metal catalysts that drive hydrogen evolution reactions (HERs) and dye-sensitized solar cells (DSSCs), transition metal selenides (TMSs) stand out due to their unique electronic properties and tunable morphology. Herein, the multicomponent selenide CuSe-Co3Se4@VSe2 was successfully synthesized by doping with metal element vanadium and selenization on the copper-cobalt carbonate hydroxide (CuCo-CH) template. CuSe-Co3Se4@VSe2 exhibited the dandelion-like cluster structure composed of hollow nanotubes doped with VSe2 nanoparticles. Due to the unique structure and the synergistic effect of various elements, CuSe-Co3Se4@VSe2 showed excellent alkaline HER and DSSC performances. The DSSC based on CuSe-Co3Se4@VSe2 exhibited an impressive power conversion efficiency (PCE) of 9.64 %, which was much higher than that of Pt (8.39 %). Besides, it possessed a low HER overpotential of 76 mV@10 mA cm−2 and a small Tafel slope of 88.9 mV dec−1 in 1.0 M KOH. © 2024 Elsevier Inc.
