“…The hydrogen of the hydroxy group (−OH) and the hydrogen (Hα) of the benzyloxy group (ArC(Hα) 2 O−) shift to Oσ and Cr, respectively. In other words, the H of the −OH group and Hα of the ArC(Hα) 2 O– group interact with Cr 2 O 3 , which weakens bonds of the C–Hα and O–H. ,, Consequently, besides the fact that UV light and visible light can be used for photocatalytic selective transformation of alcohol, the alcohol transformation can also be driven by the heating effect of thermocatalysis . On the other hand, CdS, as a very classic photocatalyst, has a good application in hydrogen generation in water decomposition and redox processes. , Under visible light illumination, CdS can be photoexcited and generate electrons and holes, electrons participate in the reduction reaction, and holes participate in the oxidation process.…”
