%X La-N co-doped TiO2 photocatalyst was synthesized by a sol-gel method, which used tetrabutyl titanate (TBOT) as the Ti resource, lanthanum nitrate as the La resource and urea as the N resource. The performance in the photocatalytic oxidation degradation of malachite green was investigated. The results showed that the reaction could be reasonably represented by first order kinetics, and a kinetic model was established; the reaction order of voltage (0.9358) was higher than that of pH (0.6119) and that of initial concentration (0.335), indicating that voltage has the greatest impact on the reaction. The model data fitted well with experimental data(R2 0.910-0.9961), which indicates that the kinetic model can well describe the process of photocatalytic degradation of malachite green.
