What “photocatalysis” means

Wiktionary · Wikipedia

photocatalysis

nounCatalysis by a photocatalyst

Full entry on Wiktionary →

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 upon irradiation with UV- or visible light generates electron–hole pairs that generate free radicals. Nanophotocatalysis is the specialization of photocatalysis in the nanoscale.
