Abstract
For studying the application of photocatalysis in cleaning organic synthesis, the use of hole selective oxidation of organic compounds is explored, and photogenerated electrons are applied to reduce hydrogen for producing new hydrogen. The reaction is carried out at normal temperature and pressure, the reaction material is simple, and the by-product is clean energy hydrogen. By replacing the Mn2+ that is commonly used in this type of experiment as Ce3+, from the experimental results, it is found that the replacement results have a better effect on the stability and adaptability of the system. The experimental water system was changed into organic solvent system, and it was found that the utilization range of photocatalysis in organic synthesis could be greatly expanded, and some reactions that the traditional chemistry can hardly have may occur. In this part, toluene is used as a reactant and also a solvent, and a coupling reaction between the self-dehydrogenation and the molecular reaction is used to generate the benzyl chloride. The experimental results show that, on the one hand, the reaction does not need to consume energy; on the other hand, it can produce hydrogen. Based on the above research, the conclusion is drawn that it saves the complex steps and environmental pollution of the traditional chemical synthesis.
