Study Data from Dankook University Update Knowledge of Chalcogens (Synergistic improvement of oxygen reduction reaction on gold/cerium-phosphate catalysts)

By a News Reporter-Staff News Editor at Life Science Weekly -- Investigators publish new report on Chalcogens. According to news reporting originating from Chungnam, South Korea, by NewsRx correspondents, research stated, "The main challenge in fuel cells lies in improving slow oxygen reduction reaction (ORB.) kinetics causing low conversion efficiencies. Here, we introduce the Au/CePO4-binary nanocomposites as effective oxygen reduction catalysts in alkaline media."

Our news editors obtained a quote from the research from Dankook University, "The ORR activity comparable with Pt is achieved through the serial 4-electron reduction pathway. The bi-functionality of CePO4 is suggested to explain the remarkably enhanced activity on the Au/CePO4 nanocomposites."

According to the news editors, the research concluded: "Significantly, the own catalytic activity of CePO4 for hydrogen peroxide is demonstrated, validating synergistic effects with Au for complete ORB.."
