本文首次以自制的B/S/TiO2粉末颗粒为原料采用水热法制备出了B/S/TiO2纳米管,再使用巯基乙酸为双管能链连接B/S/TiO2纳米管(B/S/TNTs),最终制得一种新型.PbS量子点复合的B/S/TiO2纳米管(PbS/B/S/TNTs)材料.使用X射线衍射仪、透射电子显微镜、紫外-可见分光光度计以及X射线光电子能谱仪等对样品晶型、形貌、光谱吸收范围和表面进行了表征.结果表明少量B和S掺杂对TiO2晶型、形貌没有影响,PbS/B/S/TNTs吸收光带边相对于纯TNTs明显红移,提高了样品对太阳光的利用率.在λ>420nm的光照下,使用酸性红3R染料对样品光催化特性进行研究,表明PbS/B/S/TNTs光催化性能明显高于PbS/TNTs.
