영문 초록

We prepared the nano-sized TiO₂ particles by the diffusion flame reactor and investigated the effects of several process variables on the generation and transport properties of TiO₂ particle. As the length from the tip of diffusion flame reactor increases, the size of TiO₂ particle increases by the coagulation between particles. The structure of TiO₂ particles prepared is almost found to be anatase. It was found that the TiO₂ particle size depends more largely on the change of reactor temperature than on the change of inlet TiCl₄ concentration. By the photo-degradation experiment of phenol and toluene with the prepared TiO₂ particles, we found that the photo-degradation efficiencies of phenol and toluene change, depending on the process variables such as size of TiO₂ photocatlysts, concentration of phenol or toluene. Degradation efficiencies of phenol and toluene was above 90 % in our experiments in 60 minutes.
