Abstract: The features and recent progress of mathematical model of photocatalytic reactor are introduced. Four key factors in establishing mathematical model of photocatalytic reactor: illumination arrangement，radiation field，reaction kinetics，and mass transfer are discussed. Through the analysis of modeling theory used to build mathematical model of photocatalytic reactor， the existing problems and future research priorities are presented.
