摘要:
以双(乙酰丙酮基)二异丙基钛酸酯与双-［γ-(三乙氧基硅)丙基］ 四硫化物为起始材料，通过水解缩合反应合成实心TiO2-SiO2纳米微球；将这些微球经碱性水热反应和后续高温煅烧，制备分级中空结构TiO2纳米微球光催化剂。通过TEM、DLS、FT-IR、EDS、XRD等表征手段对其形貌、单分散性、组分及晶体结构进行表征测试与分析；探讨碱性水热条件对分级中空结构形成的影响机理；研究煅烧温度对光催化剂性能的作用；通过罗丹明B的光催化降解实验来评估光催化剂的活性，并与商用P25进行对比。结果表明：所得纳米微球表面有明显的刺突、单分散性好，以钛酸盐为主要成分；钛酸盐的重结晶与二氧化硅的向内蚀刻是形成分级中空结构的关键；经500 ℃煅烧，所得催化剂保持分级中空结构，转变为锐钛矿相TiO2；其光催化性能卓越，对罗丹明B的降解速率常数 k 可达113.49×10-3·min-1 ，是实心结构的3倍，是P25的1.45倍。分级中空结构TiO2纳米微球光催化剂的制备方法简单有效，为光催化降解染料的研发提供了重要参考和理论指导。
