【Abstract】 The theory of vapor-phase synthesis of nanoparticles was given. It related to the form of nuclear, control particle diameter and nano- particle aggregation. The preparation techniques and progress were sorted by the different modality (solid,liquid,gas) of precursors,and summarized the characteristics of each method. The characters of vapor-phase synthesis of nano-structured materials is important,which relate to small particles,non-agglomerated and without treatment after formed. Now,it has been the main method of preparation nano-particles. With the development of technology and advancement of material,the industry of vapor-phase synthesis of nano-structured materials will have a good future.更多还原
