摘要
高效的可见光响应型光催化剂一直是光催化领域的研究热点。本文采用溶胶一凝胶法制备了氮掺杂TiO2累托石复合光催化剂，复合催化剂显示良好的可见光催化性能。结合催化剂的可见光催化性能，分析了一系列制备条件对催化剂光催化性能的影响。当N：Ti比为1：4时，Ti/累托石为15mmol／g，恒流蠕动泵转速3rpm，离心水洗后pH值2．0-2．5，400℃下焙烧的样品显示较好的可见光催化效果。
Efficient visible light-responsive photocatalyst has been a hot research topic in the field of photocatalyst. In this paper, nitrogen doped TiO~/rectorite composite photocatalyst was prepared by the sol gel method, and the effect of preparation conditions according to the visible light catalytic performance was analyzed. When N/Ti is 1：4, TVRectorite is 15mmoVg,the race of the pump is 3rpm,the pH after centrifugation is 2.0-2.5,and calcined at 400~C, the sample show better photocatalytic propertieso
