영문 초록

In this study, we prepared nano-sized TiO₂ particles for various process variables by the diffusion flame reactor and we collected TiO₂ particles by thermophoresis. It is found that the size of TiO₂ particles increases, as the flame temperature or the inlet TiCl₄ concentration increase or the total gas flow rate decreases. We investigated the photo-degradation of phenol wish the prepared TiO₂ particles. We found the optimum amounts of TiO₂ photocatalysts for our experimental apparatus and investigated the photo-degradation efficiencies of phenol, changing the process variables such as size of TiO₂ photocatlysts, phase ratio of rutile/anatase, concentration of phenol, input ratio of O₂. Degradation efficiencies of phenol were almost 95% in 15 minutes for the standard conditions of our experiments.
