Study of the Coupling Effect of Multiple Factors on the Photoreaction Process Based on a Standard Photoreactor

Accurate,stable, and reproducible photocatalytic reaction systemsremain a major challenge when performing photocatalytic mechanismstudies. In this paper, we designed and built a standard photocatalytic reactor to realize the precise adjustment of each parameter relatedto the photoreaction to meet the demand for the accurate study ofphotochemical reaction mechanisms and can realize the personalizedsettings for different photochemical reactions. Based on this standardreactor, the influence of each independent parameter on the conversionrate of the reaction was studied based on the model reaction of 9,10-diphenylanthraceneoxidation, and a mathematical model of the coupling influence of multiplefactors to the photochemical reaction was obtained using the dimensionlessdata processing method. The mathematical model can help to carry outthe coordinated selection of various parameters of photochemical reactions,reduce the reaction cost, and improve the reaction efficiency. Furthermore,we demonstrate the simplicity and accuracy of this reactor in measuringand calculating the quantum efficiency of photochemical reactions.This work is of great guidance to exploring the basic principles ofphotochemical reactions, the selection of reaction parameters, andthe construction of photochemical reactors.
