Three-dimensional (3D) core-shell heterostructured NixSy@MnOxHy nanorods grown on nickel foam (NixSy@MnOxHy/NF) were successfully fabricated via a simple hydrothermal reaction and subsequent electrodeposition process. The NixSy@MnOxHy/NF shows outstanding bifunctional activity stability for hydrogen evolution oxygen reaction, as well overall-water-splitting performance. main origins are the interface engineering of NixSy@MnOxHy, shell-protection characteristic MnOxHy, 3D open nanorod...
Abstract Alloying is a well‐accepted strategy for modulating the electronic structures of catalyst materials. Compared to disordered solid‐solution alloys, intermetallic compounds feature ordered atomic arrangements and provide unique platform with rich diverse resource study relationships among chemical composition, structure, properties. Unfortunately, it still challenging synthesize nanostructures catalysis research. In this study, series silicides (PtSi, RhSi, Ru 2 Si 3 , IrSi),...
CdS-based 3D nano/micro-architectures, their formation mechanism and tailoring of properties for visible light induced photocatalytic activities in energy environmental applications are presented.
Exploring highly active and stable bifunctional water-splitting electrocatalysts at ultra-high current densities is remarkably desirable. Herein, 3D nickel-iron phosphides nanosheets modified by MnOx nanoparticles are grown on nickel foam (MnOx /NiFeP/NF).
