摘要

制备了晶体介孔二氧化钛颗粒,并对其在可见光下的光催化活性进行了研究。一种新颖的方法,包括在阳离子表面活性剂存在下的二氧化钛低温结晶技术,提供具有结晶壁的介孔二氧化钛颗粒。所制得的二氧化钛在可见光(>440 nm)照射下具有较强的光催化活性,吸收阈值明显向长波方向偏移。

Preparation and Photocatalytic Activity under Visible Light Irradiation of Crystalline Mesoporous Titania Particles
Crystalline mesoporous titania particles were prepared and their photocatalytic activity under visible light irradiation was investigated. A novel method including a low-temperature crystallization technique of titania in the presence of cationic surfactants supplied mesoporous titania particles having crystalline walls. The obtained titania showed an absorption threshold drastically shifted to the longer wavelength side and a photocatalytic activity under visible light (>440 nm) irradiation.
