中文摘要： 金属复合氧化物在催化，陶瓷以及磁性材料方面有着广泛的应用，材料的形貌特征及其纯度直接影响其性能，采用简易的方法控制合成具有特定形貌特征的超纯氧化物材料是目前的热门课题之一。本研究小组在无法完成基金原定计划（基金资助的金费无法购买手套箱）的同时，开展了单分子前驱体法制备超纯复合氧化物纳米材料和水热/溶剂热法控制合成具有特定形貌的（复）氧化物相关的研究，并将合成的材料应用于催化、陶瓷和能源储存。结果表明：利用单分子前驱体法合成的钛基复合氧化物可以作为性能优良的电子陶瓷材料；利用单分子前驱体法合成的ZnMn2O4材料表现出优良的嵌/脱锂性能；利用溶剂热法一步法合成的铁基氧化物/C复合材料作为锂离子电池负极材料表现出高的比容量、良好的循环性能和倍率性能；水热法合成的氧化物具有优良的光催化性能。本研究项目的完成，为合成具有特定结构特征的超纯金属氧化物提供了新的途径，为（复）氧化物材料的应用开辟了新的方向。在基金的资助下，研究小组发表了SCI收录得论文9篇（1区和2区论文各2篇），参加会议4次，还有2篇论文已经投稿。另外，基金资助了2名研究生和5名本科生的毕业论文，研究经费使用合理。

英文摘要： Mixed metal oxides have extensive applications in catalysis, ceramics and magnetic materials. The morphologies and the purity of the materials have important effect on their properties. Morphology-controlled synthesis pure mixed metal oxides via simple synthesis routes have received tremendous reseach interest recently. Our group have focused on the investigations on the preparations of pure mixed metal oxides nanometerials via single source precursor route and morphology-controlled synthesis pure mixed metal oxides via hydrothermal/solvthermal route. At the same time, we have also focused on the study on the applications of the synthesized materials in ceramics, energy stroge and catalysis. It is demonstrated that the synthesized Ti-based mixed metal oxides via single source precursor route show good properties in ceramics materials; the synthezied ZnMn2O4 via single source precursor route shows good lithium stroge property; the obtained Fe-based mixed metal oxides/C composites as anode materials for lithium ion batteries show high specific capacity, good capacity retension capability and good rate capability; and the synthesized mixed metal oxides via hydrothermal synthesis route show good photocatalytic properties. After finishing the study plan, we have designed a new route for synthesis pure mixed metal oxides with special structure and extended the applications of the mixed metal oxides. With the supporting of the NNFSC, we have published 9 papers (SCI) and attended 4 symposiums on lithium ion batteries (international or national), we have also submited two manuscripts to the international journals. In addition, two master students and five undergraduates have finished their thesis with the NNFSC supporting.
