Hydrothermal Synthesis and Photocatalytic Properties of Bi2WO6
Source abstract
Abstract
水热法合成了Bi 2 WO 6 粉体, 并采用XRD、FESEM及UV-Vis分光光度计对样品进行表征, 研究了不同合成条件对产物形貌和催化性能的影响. UV-Vis漫反射谱表明产物在紫外和可见光区域均有吸收. 样品的光催化性能通过降解RhB溶液来评价. 结果表明: 180℃, pH=2下合成24h获得的Bi 2 WO 6 紫外光催化性能最好, 反应速率常数为0.03688/min. 还讨论了不同pH值对合成样品催化性能的影响. 催化剂的稳定性实验通过180℃, pH=2下合成24h获得的Bi 2 WO 6 多次催化实验来评估, 结果表明4次循环实验后, 样品的催化性能未有明显地衰减. 在可见光下照射150min, 催化剂对染料的降解率达到38%.
