In order to improve the visible light response and reaction efficiency of nitrogen-doped TiO2 set urea as nitrogen source, and silica gel as the load reagent adopt sol-gel method to prepare powder of nitrogen-doped TiO2 supported on SiO2 , use equal volume impregnation method to load MnO2 on catalyst, and then obtain the composite photocatalyst after drying, and roasting .The prepared composite catalysts were characterized by XPS, TEM, SEM, XRD and other methods. Moreover, the photo-catalytic activity of the composite catalysts under visible-light region was tested, and the influences of nitrogen content and calcinations temperature on the photo-catalytic activity were investigated. The results show that:(1) the range of light response of modified composite catalyst was expanded from ultraviolet region to visible-light region, which results in high visible-light catalytic activity in the degradation of methyl orange.(2) Through the mechanism of photo-catalytic reaction and the treatment effect analysis, MnO2 as catalytic resulting O2 can be served as a good electronic capture agent and improve the reaction efficiency.(3)With the reduction of nitrogen content,and the increase of calcination temperature, the visible-light catalytic activity was weakened.(4) The activity of catalyst was reused six times, without significant reduction and had excellent efficiency and stability.
