A novel high-performance Sm-N-P-TiO₂ nano-photocatalyst was successfully prepared by a modified sol-hydrothermal technique.Influence of condition factors on the photocatalytic degradation of 4-chlorophenol(4-CP) solution under simulated sunlight irradiation was investigated.Comparative research on the photoactivities of different catalysts was also carried out.The degrading reaction fits the first-order kinetics well under experimental conditions,and the degradation rate decreases with the increase of solution concentration.After irradiation under a 500 W Xenon lamp for 2 h,4-CP completely decomposed with the first order reaction rate constant(K_app) of 5.32×10^-2 min^-1 under the such conditions as initial concentration of 4-CP of 40 mg/L,Sm-N-P-TiO₂ dosage of 1.5 g/L,pH value of 5.2,solution temperature of 36℃.The photoactivity of Sm-N-P-TiO₂ is 3.49 times that of mixed-phase titania(P25).The TOC removal efficiency reaches 96.8%.
