Summary: This study investigates the stochastic feature evolution in photocatalytic systems and proposes a statistical model to describe the uncertainties of light absorption, charge carrier migration, and surface reaction. The results show that the density distribution of surface electrons changes from skewed to approximately uniform distribution with increasing incident photon density. The rate-determining step of surface reactions shifts from charge carrier kinetics to reactant activation processes with the rise in system temperature. By optimizing the operational parameters and active site density, the electron-capturing probability of active sites can be significantly increased. The established model is validated by experimental photoactivity results.
