摘　　要：以TiO2/α-ZrP复合材料为可见光光催化剂,采用氙灯模拟可见光,研究了TiO2/α-ZrP复合材料对有机染料罗丹明B的光催化降解情况。试验探究了TiO2的掺杂量、反应时间、染料浓度、光催化剂用量、染液pH值等对光催化降解罗丹明B的影响。结果表明,当TiO2的掺杂量为17%时,TiO2/α-ZrP复合材料的光催化活性最高。浓度为6×10^-5 mol/L的罗丹明B溶液的最佳降解条件为:染液初始pH值为4,TiO2/α-ZrP复合光催化剂质量浓度为3.6 g/L。The photocatalytic degradation of RhB by TiO2/α-ZrP composites is studied using xenon lamp to simulate visible light.The effects of doping amount of TiO2,reaction time,initial dye concentration,photocatalyst dosage and the pH value on the degradation of RhB are investigated in detail.The results show that the photocatalytic activity of TiO2/α-ZrP is the highest when the doping amount of TiO2 is 17%.The optimum degradation conditions of RhB solution with the concentration of 6×10^-5 mol/L are as follows:the initial pH value is 4 and the dosage ofα-ZrP/TiO2 is 3.6 g/L.
