Synthesis and Characterization of Highly Visible-light Active Monoclinic Mesoporous BiVO4
Source abstract
Abstract
利用纳米铸造法, 以立方有序介孔分子筛MCM-48为硬模板, 550℃成功制备了结晶良好的纯相单斜介孔BiVO 4 . 采用XRD、TEM、BET及UV-Vis光谱分析对样品的结构进行了表征, 结果表明: 与水热法制备的大颗粒样品相比, “纳米铸造”介孔BiVO 4 的平均孔径为16.8nm, 孔体积为0.1 cm 2 /g, 比表面积高达22.9 m 2 /g, 有效减少了光生电子和空穴复合的几率, 在可见光范围内表现出优良的可见光催化活性, 90min内对乙基黄原酸钾的光催化降解率高达78%.
