摘　　要：采用液相法(溶胶-凝胶法)在阴离子交换树脂和乙醇溶剂的辅助作用下直接合成纳米级的金属氧化物晶体和掺杂的金属氧化物晶体,经乙酸异戊酯为溶剂共沸干燥后得到高分散性的纳米微粉。电子显微镜和X衍射光谱的分析,证实了这些高分散性纳米微粉具有明确的晶体结构,并且表现出很高的光催化活性和抗菌灭菌的性能。The solution method, such as the sol-gel process,could directly synthesize nano-scale metal oxide crystal and dope nano-scale metal oxide crystal under assistance of anion-exchange resin and or- ganic solvent. The synthesized nano-scale crystals were dried through the azeotropic distillation using iso amyl acetate as azeotropic solvent and a highly dispersed powder was obtained. The analysis that conducted on transmission electron microscope （TEM） and X-ray diffractometer （XRD） demonstrated the nano scale powder did possess distinctly crystalline structure, and showed a high photo-catalysis and anti-bacterial that only crystal had.
