Molybdenum oxides possess a variety of potential applications in chemical synthesis, petroleum refining, recording media and sensors because of its unique catalytic activity, elctroluminescent and photoluminescenceand. It is vital for the performance of molybdenum oxides to regulate and control the morphology, size and structure of the crystal of molybdenum oxides. Recently the polymeric system has been adopted as template or confinement reactor for nao-and micro-fabrication. Polymers with differrent morphologies and tunable sizes in the different conditions can be modified to enhance interactions and be easy removed by dissolution with a solvent or by calcification. Based on the unique properties of molybdenum oxides and polymer application in the biomineralization of inorganic compounds, a brand-new comprehensive subject named as "PEO polymer-controled synthesis of molybdenum oxides: structure diversity and mechanism research" has been brought forth by us. In this subject, using "Molybdenum oxides nano materials assembly and crystallization process " as the main line, some basic researches including the conformation of molybdenum precursor solution, the Nucleation and growth of molybdenum oxides in the PEO polymeric systems, and the biomineralization of molybdenum oxides would have been studied out.Through the study mentioned above, we can obtain the regulation measures of molybdenum oxides with multi-morphologies and comples structures, fulfill the controllable synthesis of special molybdenum oxides,and ultimately reveal the structure diversity and the regulation mechanism of molybdenum oxides in the PEO polymeric systems. Furthermore,the novel synthesization technology for nano-and micro-molybdenum oxides and organic/inorganic hybrid materials would come into being ,and be also employed for growth of a variety of nano- and micro-transition metal oxide materials in the future.
