过去十年,纳米点,纳米棒和纳米线的可控合成取得了巨大进展,这源于纳米材料尺寸和形貌可以改变材料的性质.为了更好调控纳米材料的形貌,根据已经取得的实验结果去研究纳米材料的合成机理成为研究的热点.在本综述中,我们系统了归纳了化学可控合成纳米材料的方法,包括共沉淀方法、溶胶-凝胶法、微乳液法以及水热/溶剂热法.而且,根据纳米材料的合成机理,我们总结并分析了均核合成机理、异核合成机理、软模板诱导机理、液体-液体-同体合成机理以及气相-液相-固相合成机理.另外,对纳米材料的在纳米器件、光催化、太阳能电池以及纳米记忆材料的应用进行了介绍.本综述对材料科学家和化学家在可控合成纳米材料核更好地理解纳米材料的合成机理必有指导作用.

Much progress has been made over the past ten years on the controlled synthesis of nanomatefials including nanodots,nanorods and nanowires due to size and shape-dependent properties.For the sake of better tunable morphologies of nanomaterials,it is important to investigate the nanomaterial formation mechanism based on some outcomes obtained upto date.Hence,this review will summarize recent scientific articles and govemment pubhcations that address the uses of wet chemistry with some emphasis on solvothermal synthetic mthods and formaion mechanisms.Particularly,the reported method include coprecipitation method,so-gel method, microemulsion method and hydrothermal/solvothemal method.On the other hand,some formation mechanism of hornogeneous-nuclear formaiton mechanism,heterogeneous-nuclear formation mechanism,vapor-liquid-solid formation mechanism,liquid-liquid-solid formation mechanism,surfactant -induced formation mechanism and template-con-trolled formation mechanisms.Meanwhile,some applications of nanodevices, catalyst, solar cell and so on are also discussed in this review.This current review would be useful for material scientist and chemists to controllederably synthesize nanomaterials and better understand the formation mechanism for nanomaterials.
