Morphological effect of bismuth vanadate (BiVO4) on visible light-driven catalytic degradation of aqueous paracetamol was carefully investigated using four monoclinic BiVO4 catalysts. The catalysts with different morphologies were controllably prepared by a hydrothermal method without any additions. The prepared catalysts were fully characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and UV-Vis diffuse reflectance spectroscopy (DRS). Under the visible light irradiation, these catalysts with different morphology were investigated to degrade aqueous paracetamol contaminant. The degradation effects were evaluated based on the catalyst morphology, solution pH, initial paracetamol concentration, and catalyst dosage. Cube-like BiVO4 powders exhibited excellent photocatalytic performance. The optimal photocatalytic performance of the cube-like BiVO4 in degrading paracetamol was achieved.
使用四种单斜晶型的钒酸铋（BiVO₄）催化剂，仔细研究了钒酸铋（BiVO₄）对可见光驱动催化降解水溶液中对乙酰氨基酚的形态学影响。通过水热法在不添加任何物质的情况下可控地制备了具有不同形态的催化剂。通过X射线衍射（XRD）、扫描电子显微镜（SEM）和紫外-可见漫反射光谱（DRS）对制备的催化剂进行了全面表征。在可见光照射下，研究了这些具有不同形态的催化剂对水溶液中对乙酰氨基酚污染物的降解情况。基于催化剂形态、溶液pH值、对乙酰氨基酚初始浓度和催化剂用量评估了降解效果。立方状BiVO₄粉末表现出优异的光催化性能。实现了立方状BiVO₄在降解对乙酰氨基酚方面的最佳光催化性能。
