摘　　要：近年来过渡金属锰氧化物研究火热,特别是对二氧化锰进行了广而深的研究,而Mn_3O_4作为另一种潜在的多功能性锰系氧化物(超级电容器、催化剂及医学领域均有涉及)尚未被系统研究。对最近5年来该材料的主要研究方向及应用领域进行分类整理后发现:纳米Mn_3O_4多与导电性良好的碳纤维、碳纳米管、石墨烯等碳材料相结合作为超级电容器电极材料来研究;催化方面,该材料多用于结合类芬顿法降解有机废水以及作为电催化催化剂用来产氢;医学领域高分散性和小尺寸Mn_3O_4材料被用于生物体内成像和靶向治疗的药物载体。因Mn_3O_4应用领域拓展的核心要素在于纳米技术,故对其形貌和尺寸的控制将成为今后研究的重点。In recent years,transition metal manganese oxides have been hotly studied,and in particular,manganese dioxide has been extensively and deeply studied,but another potential multifunctional manganese oxide,Mn3O4 which is involved in supercapacitors,the catalysts and medical fields has not been systematically studied.The main research contents and application fields of nano-Mn3O4 in the last five years has classified,As a result,it was found that the nano-Mn3O4 is mostly combined with carbon materials such as carbon fibers,carbon nanotubes,and graphene,which are well-conducted,as supercapacitor electrode materials.In terms of catalysis,this material is mostly used for the degradation of organic wastewater by the combination of Fenton-like processes and as an electrocatalytic catalyst for the production of hydrogen.Medicine,highly dispersible and small-size nano-Mn3O4 is used as drug carriers for in vivo imaging and targeted therapy.Because the core element of the application development of Mn3O4 is nanotechnology.The control of its morphology and size will become the focus of future research.
