Sonication strategy for anchoring single metal atom oxides (W, Cu, Co) on CeO-rGO for boosting electrocatalytic oxygen evolution reaction.

In the field of electrocatalysis, single-atomic-layer tungsten, copper, and cobalt oxide on CeO, ethylene diamine (ED) and reduced graphene oxide (rGO) supported materials shows tremendous potential. Despite the enormous interest in single metal atom oxide (SMAO) catalysts, it is still very difficult to directly convert readily available bulk metal oxide into single atom oxide. It is crucial and tough to create high performance materials for the oxygen evolution reaction (OER) in an alkaline environment.

ZnSe and CdS Co-Sensitized TiO Nanorod Arrays as Photoanodes for Bias-Free Solar Hydrogen Evolution.

The efficient charge separation and surface state reactions are significant in enhancing the efficiency of photoelectrochemical hydrogen evolution. Herein, we report a ternary heterostructure consisting of CdS/ZnSe sensitized TiO nanorod as a photoanode. The heterojunction photoanode considerably widens the photon absorption spectral range and thereby enhances the photocurrent density up to 2 mA/cm at 1.
