In chemistry, photocatalysis is the acceleration of a photoreaction in the presence of a photocatalyst, the excited state of which "repeatedly interacts with the reaction partners forming reaction intermediates and regenerates itself after each cycle of such interactions." In many cases, the catalyst is a solid that … See more Early mentions (1911–1938) The earliest mention came in 1911, when German chemist Dr. Alexander Eibner integrated the concept in his research of the illumination of zinc oxide (ZnO) on the bleaching of the … See more Photoactive catalysts have been introduced over the last decade, such as TiO 2 and ZnO nano rodes. Most suffer from the fact that they can only perform under UV irradiation due to their band structure.

WebPhotocatalysts. Photoredox catalysis is a powerful tool in organic chemical synthesis that utilizes visible light to power a chemical reaction. Widespread adoption of visible light photoredox catalysis has been dependent on access to photocatalysts and a reliable light source. We’re pleased to support your photocatalysis endeavors to create ... Photoredox catalysis is a branch of photochemistry that uses single-electron transfer. Photoredox catalysts are generally drawn from three classes of materials: transition-metal complexes, organic dyes, and semiconductors. While organic photoredox catalysts were dominant throughout the 1990s and early 2000s, soluble transition-metal complexes are more commonly used today.
WebPhotocatalysis is an ecofriendly technique that emerged as a promising alternative for the degradation of many organic pollutants. The weaknesses of the present photocatalytic system which limit their industrial applications include low-usage of visible light, fast charge recombination, and low migration ability of the photo-generated electrons and holes.
