| 초록 | We compared the plausible reaction mechanism and quantitative efficiency of highly self-organized TiO 2 nanotube (ntTiO 2 ) film with TiO 2 powder. Film was fabricated by electrochemical potentiostatic anodization of titanium thin film in an ethylene-glycol electrolyte solution containing 0.3 wt% NH 4 F and 2 vol% deionized water. Nanotubes with a pore size of 80-100 nm were formed by anodization at 60 V for 3 h. Humic acid (HA) was degraded through photocatalytic degradation using the ntTiO 2 film. Pseudo first-order rate constants for 0.3 g of ntTiO 2 , 0.3 g TiO 2 powder, and 1 g TiO 2 powder were 0.081 min #x2212;1 , 0.003 min #x2212;1 , and 0.044 min #x2212;1 , respectively. HA adsorption on the ntTiO 2 film was minimal while adsorption on the TiO 2 powder was about 20% based on thermogravimetric analysis. Approximately five-fold more normalized OH radicals were generated by the ntTiO 2 film than the TiO 2 powder. These quantitative findings explain why ntTiO 2 film showed superior photocatalytic performance to TiO 2 powder. |
