【摘要】 综述了近 5年来金属氧化物纳米材料的制备方法、研究现状 ;讨论了这些方法的优缺点。指出液相法 ,尤其是溶胶 -凝胶法、沉淀法、水解法、微乳液法、水热溶剂热法等是目前制备纳米金属氧化物材料最广泛应用的方法。而超声技术、微波辐射技术、交流电沉积技术、超临界流体干燥技术、非水溶剂水热技术等新技术与传统液相法的有机结合 ,是制备高纯度、小粒径、均匀分散的金属氧化物纳米粉体的最有前途的方法。最后对金属氧化物纳米材料研究的发展方向提出了展望。更多还原

【Abstract】 In this paper,the preparative methods and research status of metal oxide nanomaterials in latest five years are reviewed,meanwhile their Pros and Cons are also discussed.It is Shown that the liquid phase methods,in which particularly methods of the sol-gel,deposition,micro-lacteous,hydrothermal/solvothermal reaction and hydrolyze,should be mentioned,as the most wildly used method in the present.In addition,the effective combination technologies of ultrasonic,microwave,alternating current deposition,supercritical fluid drying with traditional liquid methods is the most promising one to prepare high purity,small size and well-proportioned dispersing nano-particles.Development trend of metal oxide nanomaterials is reviewed lastly.更多还原
