好像也不是单纯讲Ag催化的吧?
In the dark, AgNO3 can adsorb CH3SH immediately to form Ag-SCH3 that is then decomposed by the scission of C-S to generate the Ag-S species (Ag2S, Ag4S2, AgSH, etc). Under UVA illumination, Ag-SCH3 and other Ag-S species can be oxidized into AgSO3CH3 and Ag2SO4 that can also react with CH3SHto form Ag-SCH3 again and release two final products of HSO3CH3 and H2SO4. It can be seen that with three core intermediates of Ag-SCH3, AgSO3CH3, and Ag2SO4, the chemisorption and photocatalytic reaction are continuously preceded under UVAillumination to degrade gaseousCH3SH into two aqueous acids as its final products.
