Nd3+-doped TiO2 nanosphere is synthesized by template-free method (recombined coprecipitation with hydrothermal method), which possesses anatase TiO2 and TiO2(B) nanosphere structure produced during hydrothermal process. After doping different content neodymium ions, the excellent photocatalytic performance of doped samples have been confirmed by subsequent photodegradation experiments, in which the 1.0 mol% Nd3+-TiO2 sample has been considered the optimum choice owing to its high degradation of 99.14% under visible light irradiation in 120 min, it almost completely degraded methylene blue in 80 min under simulated sunlight. This conclusion is contributed to further industrial application of TiO2 in the degradation of sewage.
