英文摘要： The project aims at tunable preparation of ferrite nano-materials.Selective oxidation of cyclohexane is selected as probe reaction and following studies will be carried out. (1) A series of magnetic materials will be prepared and well characterized. Their catalytic performances on selective oxidation of cyclohexane will be investigated carefully and relationships between structures and performances of the ferrites will be disclosed. Based on this, performances of ferrites will be optimized by tuning their composites and structures.(2) The methods and conditions for preparation of the ferrites will be also optimized to bring about tunable preparation of the ferrites.(3) Reaction conditions for cyclohexane oxidation will be optimized. Based on the above studies, a green catalytic system with high efficiency and selectivity for cyclohexane oxidation will be founded.The potential capacities and advantages of the ferrites as catalysts for selective oxidation of other hydrocarbons will be disclosed and the theoretical and experimental supporting will be provided for design, preparation and optimizing of the ferrites.
