金属有机骨架化合物(MOFs)是由有机配体和金属节点通过自组装形成的一类具有周期性结构和较大比表面积的材料。目前,选择MOFs材料作为前驱体,经高温焙烧合成纳米金属氧化物或纳米复合金属氧化物材料是一大研究热点。综述了近年来以Co基配位聚合物为前驱体制备纳米Co_3O_4或Co_3O_4/碳纳米复合材料的方法,以及Co_3O_4纳米材料在锂离子电池负极材料、超级电容器、电催化析氧反应、气敏材料及催化剂材料等研究领域的应用,并对其今后的发展进行了展望。

Progress on Micro/Nano Co3O4 Functional Materials Derived from Co-Coordination Complexes

The metal-organic frameworks (MOFs),which possess a periodic network structure with self-assembled by organic ligand and metal node,and ultra-high surface area,have been utilized as precursors via calcination process to generate structured nanoporous metal oxide or porous metal oxide/carbon materials composite.Fabrication of the metal oxides materials from MOFs precursors has attracted intensive research attention in the materials field.In this paper,we summarized the recent progresses of Co3O4 nanomaterials derived from precursive Co-based coordination polymers.We have reviewed the synthesis methods for metal oxide or porous metal oxide/carbon materials composite.In addition,we also summarized the applications of Co3O4 nanomaterials in the field such as lithium ion battery,supercapacitor,oxygen evolution reaction(OER) catalyst,gas sensing materials and catalysts materials.Furthermore,the future development and challenges of Co3O4 materials derived from coordination complexes were discussed.
