摘要： 以硼酸和钛酸丁酯为原料,采用水热法一步合成了B掺杂的纳米TiO2. 采用X射线衍射、紫外-可见光谱、透射电镜以及X射线光电子能谱对所得样品进行了表征. 结果表明,该方法制备的B-TiO2具有明显的可见光吸收,并且少量B的掺杂不会对TiO2的晶型和粒径造成很大影响. 掺杂的B以B-O-Ti的形式存在,有利于可见光活性的提高. 苯酚的光催化降解反应实验表明,水热法合成的B-TiO2在可见光下具有较好的光催化活性,反应5 h后苯酚降解率可达100%.

Abstract: Boron-doped TiO2 was successfully synthesized by the hydrothermal method. In the as-synthesized samples, B-O-Ti bonds were formed. Phenol degradation was used as a probe reaction to evaluate the photocatalytic activity of B-doped TiO 2 under UV and visible light, and an excellent photocatalytic activity (100% p henol degradation in 5 h) was achieved.
