摘要:
在水-醇体系中,以钛酸四正丁酯(TBOT)及葡萄糖、蔗糖或淀粉分别作为Ti及C的前驱体,通过水热过程制备了一系列C/TiO2光催化剂。FE-SEM和TEM结果表明水热过程中所形成的TiO2晶粒被包覆在前驱体所形成的C中,其尺寸约10 nm。电化学分析结果表明,C的引入抑制了TiO2光生电子-空穴对的复合几率。与纯TiO2纳米粒子相比,C/TiO2显示了对亚甲基蓝光催化降解具有良好的催化活性。
Abstract:
A series of C/TiO2 photocatalyst were prepared in a water-ethanol system through hydrothermal process,using tetrabutyl titanate,glucose,sucrose or starch as Ti and C precursor respectively.FE-SEM and TEM results show that TiO2 crystalline particles formed by the hydrothermal process are about 10 nm and are embeded in carbon which is derived from C precursor.The electrochemical analysis indicates that the introduction of carbon suppressed the recombination of photo-induced electron-hole pairs.The C/TiO2 photocatalysts showed significant improvement in activity for the degradation of methylene blue compared with pure TiO2 particles.
