Findings from Nanyang Technological University Has Provided New Data on Heavy Metals (TiO2 promoted by two different non-noble metal cocatalysts for enhanced photocatalytic H-2 evolution)

By a News Reporter-Staff News Editor at Science Letter -- Fresh data on Heavy Metals are presented in a new report. According to news reporting from Singapore, Singapore, by NewsRx journalists, research stated, "TiO2 photocatalysts modified by cobalt and nickel cocatalysts were prepared via polymerized complex method (PCM) and evaluated by photocatalytic hydrogen evolution."

The news correspondents obtained a quote from the research from Nanyang Technological University, "Hydrogen generation in 6 h for the TiO2 promoted by cobalt and nickel (0.1%Co + 0.2%Ni/TiO2) is about two times (2456 mu mol H-2) compared to that of TiO2 promoted only by cobalt (1180 mu mol H-2 for 0.1%Co/TiO2) or nickel (1127 p,mol H-2 for 0.2%Ni/TiO2), and mechanically mixed TiO2 promoted by cobalt and TiO2 promoted by nickel (0.1%Co/TiO2:0.2%Ni/TiO2 = 1:1 (m/m), 1282 mu mol H-2). The high photocatalytic H-2 evolution activity over TiO2 promoted by cobalt and nickel is ascribed to enhanced photo response due to the presence of cobalt and nickel impurity level, and effective separation of photogenerated electrons and holes due to the synergistic effect of cobalt and nickel, which serve as active sites for H-2 evolution reaction (HER) and oxidation reaction (OR) respectively."

According to the news reporters, the research concluded: "This study demonstrates a viable strategy to design more active photocatalysts for photocatalytic H-2 evolution by substituting noble metals with more abundant elements using as HER and OR cocatalysts, respectively."
