Abstract: The theory of vapor-phase synthesis of nanoparticles was giv en. 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 summa rized 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 devel opment of technology and advancement of material, the industry of va por-phase synthesis of nano-structured materials will have a good future.
