WebNov 29, 2016 · ABSTRACT. Photocatalysis, reactions carried out in the presence of a semiconductor and light, is rapidly becoming one of the most active areas of chemical … Web5.4.2 Heterogeneous Photocatalysts. Photocatalysts can be assessed based on some specific parameters. The TON of the catalyst quantifies its ability to act upon more than one set of reactant molecules. It is defined as the number of reactants that a catalyst acts upon before it degrades.
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.
