【摘要】采用水热合成法制备了典型的手里剑型钒酸铋晶体（BiVO₄）,利用硬模板法制备了介孔氮化碳材料（mpg-C₃N₄）,运用超声分散的方法将二者复合,制得mpg-C₃N₄/BiVO₄异质结光催化剂。文章考察了其在可见光条件下降解复方磺胺甲恶唑的效果,并探讨了影响降解效果的因素。更多还原

【Abstract】 A typical shuriken-like bismuth vanadate crystal（BiVO₄） is made by hydrothermal synthesis, and mesoporous carbon nitride material（mpg-C₃N₄） is made by the hard film method. Then the above two substances are combined together by ultrasonic dispersion, which produces mpg-C₃N₄/BiVO₄ heterojunction photocatalys. In the following, its effectiveness on degrading compound sulfamethoxazole under visible light is tested, and the factors affecting the degradation effectiveness are discussed.更多还原
