Construction of Ni³⁺-rich nanograss arrays for boosting alkaline water oxidation

Abstract

It remains a major challenge that the rational design high-efficiency electrocatalysts are applied to water oxidation in alkaline media. In this paper, Ni3+-rich nanograss-like Mo-doped Ni3S2/NiS/VS arrays grown on a...

Branched Porous Ni3N as a Catalytic Electrode for Selective Semidehydrogenation of Tetrahydroisoquinoline

“…Water splitting driven by electric energy, especially the electric energy generated from the intermittent but sustainable energy sources such as wind and solar energy, has got much attention since it can greenly produce hydrogen that is an environmentally friendly energy carrier. − However, for water splitting, the anode end with an oxygen evolution reaction (OER) needs a high overpotential, which greatly limits the total energy efficiency for hydrogen production on the other end. − In addition, the oxygen produced at the anode end is relatively low-valuable. Thus, integrating a useful anodic reaction with low overpotential will not only improve water-splitting efficiency inducing the generation of hydrogen, but will also provide value-added products. − …”

Insights into Fe-doping effect-induced heterostructure formation for the oxygen evolution reaction

“…1 However, the sluggish catalytic kinetics of the OER with 4 electron per proton transfer steps in the reaction process severely affect the catalytic efficiency, and the development of efficient OER catalysts has a decisive impact on performance improvement. 2 IrO 2 and RuO 2 have been reported to have high OER catalytic activity, but their application is limited by the high cost and insufficient earth reserves. 3 Transition metal Ni-based catalysts have shown great potential as OER electrocatalysts in alkaline electrolytes.…”
