New photocatalysts are highly effective in synthesizing hydrogen peroxide

Recently, a team of researchers at Osaka University in Japan developed a new type of photocatalyst based on water and oxygen, interphenol-formaldehyde (RF) photocatalytic resin, which shows very high synthetic activity of hydrogen peroxide (

's team focused on a common synthetic polymer- interphenol-formaldehyde (RF) resin that can be used as a coating and adhesive, independently developed a method for synthesized RF resins using high-temperature hydrothermal methods, and for the first time found that RF resin powders modulated with this method can be used as semiconductor photocatalysts. This "out of common sense" discovery of synthetic RF photocatalytic resins, in all reported solar conversion reactions using powder photocatalysts to date, can be synthesized with the highest efficiency
