Reports Outline Photocatalytics Findings from Japan Science and Technology Agency (Effect of Hydrogen and Oxygen Evolution Cocatalysts on Photocatalytic Activity of GaN:ZnO)

By a News Reporter-Staff News Editor at Life Science Weekly -- Investigators publish new report on Photocatalytics. According to news reporting originating from Saitama, Japan, by NewsRx correspondents, research stated, "The coloading effect of H-2 and O-2 evolution cocatalysts on the overall water splitting reaction was investigated using a solid solution of GaN and ZnO (hereafter termed GaN: ZnO) as a photocatalyst. GaN: ZnO was modified with nanoparticulate Mn3O4, RuO2, and IrO2 as O-2 evolution cocatalysts and with core/shell-type Rh/Cr2O3 composites as H-2 evolution cocatalysts."

Our news editors obtained a quote from the research from Japan Science and Technology Agency, "The photocatalytic activity of the coloaded samples for overall water splitting was higher than that of the samples modified with either of the O-2 or H-2 evolution cocatalysts alone. The activity enhancement induced by coloading was comparable for the three O-2 evolution cocatalysts investigated at the optimized loading amounts. Loading of a more efficient Rh/Cr2O3 cocatalyst prepared by adsorption of Rh nanoparticles further improved the photocatalytic activity."

According to the news editors, the research concluded: "It was concluded that a simultaneous improvement in both oxidation and reduction reactions was effective at enhancing the photocatalytic activity of GaN:ZnO, whereas the reduction reactions limited the overall reaction rate of the coloaded system more significantly."
