Petal-like NiCoP sheets on 3D nitrogen-doped carbon nanofiber network as a robust bifunctional electrocatalyst for water splitting

Zhenxiang Zhan et al.

Summary: In this study, petal-like NiCoP sheets were synthesized and used as catalysts for hydrogen and oxygen evolution reactions. The NiCoP/CNNCP electrode exhibited excellent catalytic performance with lower overpotentials compared to other nickel and cobalt-based phosphide catalysts. The overall water-splitting electrolyzer assembled with NiCoP/CNNCP as bifunctional electrodes also required a very low cell voltage.

Atom Surface Dynamics of Manganese Oxide under Oxygen Evolution Reaction-Like Conditions Studied by In Situ Environmental Transmission Electron Microscopy

Emanuel Ronge et al.

Summary: This study investigates the atomic surface structure of Ca-birnessite electrodes under conditions close to the oxygen evolution reaction (OER) using environmental transmission electron microscopy. It was found that a highly dynamic state of the surface and subsurface develops in H2O vapor, but not in O-2 or inert gases. Furthermore, electron beam-induced effects show different behaviors in high vacuum and H2O environments.
