摘要(Abstract):
研究了采用阳极氧化—连续离子层吸附反应法在TiO_2上原位制备BiOBr/TiO_2纳米管阵列(BiOBr/TNTAs)薄膜,并采用SEM、XRD、XPS和电化学工作站等手段进行分析表征,以及在可见光下以BiOBr/TNTAs催化降解双酚A。结果表明:BiOBr/TNTAs薄膜比TNTAs的光催化活性更强;浸渍7次后形成的BiOBr/TNTAs有更好的光催化活性,对双酚A的降解率达81.2%,降解过程符合准一级动力学模型,反应速率常数为5.36×10(-3) min(-3) min(-1),为TNTAs的6倍。自由基捕获试验结果表明,降解过程中,·OH起主导作用。
