Interface engineering of NiP/MoO decorated NiFeP nanosheets for enhanced alkaline hydrogen evolution reaction at high current densities.

The rational design of high-performance non-noble metal electrocatalysts at large current densities is important for the development of sustainable energy conversion devices such as alkaline water electrolyzers. However, improving the intrinsic activity of those non-noble metal electrocatalysts remains a great challenge. Therefore, NiP/MoO decorated three-dimensional (3D) NiFeP nanosheets (NiFeP@NiP/MoO) with abundant interfaces were synthesized using facile hydrothermal and phosphorization methods.

Interface Engineering of NiS@MnOH Nanorods to Efficiently Enhance Overall-Water-Splitting Activity and Stability.

Three-dimensional (3D) core-shell heterostructured NiS@MnOH nanorods grown on nickel foam (NiS@MnOH/NF) were successfully fabricated via a simple hydrothermal reaction and a subsequent electrodeposition process. The fabricated NiS@MnOH/NF shows outstanding bifunctional activity and stability for hydrogen evolution reaction and oxygen evolution reaction, as well as overall-water-splitting performance. The main origins are the interface engineering of NiS@MnOH, the shell-protection characteristic of MnOH, and the 3D open nanorod structure, which remarkably endow the electrocatalyst with high activity and stability.

Phosphorus-Doped Graphene Electrocatalysts for Oxygen Reduction Reaction.

Developing cheap and earth-abundant electrocatalysts with high activity and stability for oxygen reduction reactions (ORRs) is highly desired for the commercial implementation of fuel cells and metal-air batteries. Tremendous efforts have been made on doped-graphene catalysts. However, the progress of phosphorus-doped graphene (P-graphene) for ORRs has rarely been summarized until now.

Electrocatalytic Oxygen Evolution Reaction in Acidic Conditions: Recent Progress and Perspectives.

The electrochemical oxygen evolution reaction (OER) is an important half-cell reaction in many renewable energy conversion and storage technologies, including electrolyzers, nitrogen fixation, CO reduction, metal-air batteries, and regenerative fuel cells. Among them, proton exchange membrane (PEM)-based devices exhibit a series of advantages, such as excellent proton conductivity, high durability, and good mechanical strength, and have attracted global interest as a green energy device for transport and stationary sectors. Nevertheless, with a view to rapid commercialization, it is urgent to develop highly active and acid-stable OER catalysts for PEM-based devices.
