WebJan 1, 2024 · Adsorption–Desorption Phenomena The adsorption occurs by a physical or chemical interaction of a species on the (photo)catalyst surface. The surface is called adsorbent and the adsorbed species are called adsorbates [10], [11]. Adsorbate is referred to as adsorptive before adsorbing the surface. WebAug 23, 2024 · It was generally concluded that the photocatalytic reaction was mainly caused by adsorption of the organic compounds onto the surface of the catalyst. This point was no doubt very important for strongly adsorbing substances, including dyes and pigments (El-Morsi et al. 2000; Zhang et al. 1998 ).
