광촉매 TiO2를 이용한 피리미딘계 화합물의 분해에서 TiO2의 결정성과 활성에 키치는 열처리의 영향
Effects of Heat Treatment on the Crystallinity and the Activity of TiO2 Photocatalyst for the Degradation of a Pyrimidine Derivative
Effects of heat treatment on the crystallinity and the activity of TiO2 photocatalyst for the degradation of 6-hydroxy-2-isopropyl-4-methyl pyrimidine were stydied by XRD, BET,and IR. Degussa P25 and TiO2 synthesized by sol-gel method were used. With increasing calcination tenperature, both rutile content and crystallite size increased but BET surface area and amount of surface hydroxyl decreased. Photoactivity of TiO2 was mainly affected by both rutile content and crystallite size.
