| 摘 要： | 采用TiO2溶胶-凝胶法制备了复合半导体MoS2/TiO2纳米材料,用XRD、UV-VIS-DRS、BET等手段对样品进行了表征,并以亚甲基蓝染料为探针分子详细讨论了MoS2掺杂量、染料初始浓度等对其光催化性能的影响.结果表明:MoS2/TiO2复合半导体纳米材料具有较好的可见光催化活性;当染料浓度为0.284mmol·L-1,催化剂用量为0.5 g·L-1,亚甲基蓝染料的光催化降解率为96.5%. |

| Abstract: | MoS2/TiO2 nanomaterial prepared by sol-gel process was characterized by XRD,UV-VIS-DRS,BET and so on.Meanwhile methylene blue(MB) was taken as the probe molecular to evaluate the visible light photocatalytic activity of the compound semiconductor materials.The effects of ration of MoS2 in composite catalyst,the initial concentration of methylene blue and the quantity of catalyst on the degradation rate of the methylene blue solution were investigated.The results show that the compound semiconductor materials exhibited the best photocatalytic activity being the decolorization proportion of methylene blue is 96.5% when the quantity of catalyst 0.5 g·L-1,the initial concentration of methylene blue is 0.284 mmol·L-1 under visible light. |
| Keywords: | MoS2/TiO2 visible light photocatalytic methylene blue |
