Photo adsorption
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 ).

WebJan 16, 2024 · Unlike macro-reactors, photocatalytic MRs possess a large surface to volume ratio which translates to short diffusion distance for molecules, high spatial illumination homogeneity, remarkable mass and heat transfer rates, precise control of process variables and excellent laminar fluid flow ( Yue, 2024, Yusuf et al., 2024, Zhang et al., 2024 ). The bulk electronic band structure of transition metal oxides consists of overlapping 2p orbitals from oxygen atoms, forming the lower energy, highly populated valence band, while the sparsely populated, higher energy conduction band consists of overlapping d orbitals of the transition metal cation. In contrast to metals, having a continuous band of electronic states, semiconductors hav…
