Research Abstract	This research aims to produce a visible-light active ZnO catalyst and improve the activity based on mechanochemical dopings. Nitrogen and carbon dopings in the first year and sulfur doping in the second year were performed respectively. And in the third year, composites of the doped ZnO and other oxides were prepared. The nitrogen doping was clearly observed with several analytical methods and antibacterial effect was also obtained. As to the composition, composite with TiO_2 was found to demonstrate activity under visible-light irridation.
