Cerium-Doped Nickel Sulfide Nanospheres as Efficient Catalysts for Overall Water Splitting.

The development of non-precious metal electrocatalysts with excellent activity and durability for electrochemical water splitting has always been a goal. Transition metal sulfides are attractive electrocatalysts for both hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). In this article, we designed and constructed efficient catalysts with multiple synergistic interactions and synthesized Ce-NiS@NF nanosphere using a solvothermal method.

A novel sacrificial solvent method to synthesize self-supporting CoS/NiS heterostructure catalyst for efficient oxygen evolution reaction.

Synthesizing catalysts for efficient oxygen evolution reaction (OER) with lower cost and simpler design is of significant importance to achieve sustainable hydrogen production. In this work, we propose a novel "sacrificial solvent method" for the first time. Dicobalt octacarbonyl (Co(CO)), dimethyl sulfoxide (DMSO), and Ni foam (NF) were used as the raw materials in the solvothermal process.

Constructing Hierarchical Porous MoO @Mo N@C Composite via a Confined Pyrolysis Synthetic Strategy Towards Lithium-Ion Battery Anodes.

Molybdenum dioxide (MoO ) demonstrates a big potential toward lithium-ion storage due to its high theoretical capacity. The sluggish reaction kinetics and large volume change during cycling process, however, unavoidably lead to inferior electrochemical performance, thus failing to satisfy the requirements of practical applications. Herein, we developed a molybdenum-based oxyacid salt confined pyrolysis strategy to achieve a novel hierarchical porous MoO @Mo N@C composite.
