Outline of Final Research Achievements

A convenient method for preparation of Japanese cedar char with visible-light active TiO2 was developed. It was prepared by carbonization of Japanese cedar sawdust loaded with visible-light active TiO2 doped with nitrogen, sulfur and iron. Its preparation conditions such as doping agents, materials of a ball mill and carbonization temperatures were examined. When Japanese cedar sawdust loaded with TiO2 doped with nitrogen using an alumina ball mill was carbonized at 400℃, the obtained product showed the highest performance for adsorption and decomposition for methylene blue.
