Abstract: Molecular imprinted photocatalysts were prepared by surface molecular imprinting technique. The as-prepared molecular imprinting photocatalysts were characterized by SEM, XRD and FT-IR analyses. Adsorption equilibrium data of various temperatures were described by the Langmuir, Freundlich and Temkin isotherm models. Results indicated that the adsorption equilibrium data provide a good fit to Langmuir model, and the kinetics of adsorption followed the pseudo-second-order model. A molecular imprinting photocatalyst has better photocatalytic activity on degradation of salicylic acid, the photocatalytic degradation rate could reach 66.24% under visible light, and the kinetics of photocatalytic degradation on salicylic acid obeyed second-order kinetics
