WebJan 1, 2014 · A general definition of photocatalysis, a conceptual name of photocatalytic reactions, is a chemical reaction induced by photoabsorption of a solid material, or “photocatalyst,” which remains unchanged during the reaction. Therefore, “photocatalyst” should act catalytically, i.e., without change, under light. WebNov 1, 2024 · The size of photocatalyst is essential for photocatalytic activity, however, the photocatalysts are inclined to aggregate into larger size due to their high surface energy, which in turn decreases their contact area with reactant. Considering the MXene-based materials, which are normally prepared via wet chemical etching method, consists of a ...
