One-pot hydrothermal to prepare MoO_3@TiO_2/Ti_3C_2 and research on electrochemical properties

以七钼酸铵、盐酸、二维层状Ti_3C_2为原料采用水热法制备了一种超级电容器的电极材料,并且研究了负载MoO_3对于Ti_3C_2电化学性能的影响.采用XRD和SEM对复合材料的组成和微观结构进行分析,并利用电化学工作站对材料进行电化学性能的测试,其中包括循环伏安曲线,恒流充放电曲线,阻抗和循环性能的测试.结果表明:通过引入Mo源生成MoO_3和原位生成TiO_2对材料进行改性,增加了电解液与电极材料的接触面积并形成离子通道,加快了电解液中的离子移动的速率,从而提高了材料的电化学性能.

In this study,ammonium molybdate,hydrochloric acid,2-D layered Ti_3C_2 were adopted to synthesis a supercapacitor electrode materials by one-pot hydrothermal method.Also,the influence on electrochemical performance of loading MoO_3 on Ti_3C_2was studied.In this paper,the composition and microstructure of the composite materials was characterized by XRD and SEM.Electrochemical properties of the material was conducted by electrochemical workstation,including cyclic voltammetric curves（CVs）,galvanostatic charge-discharge curve（GCD）,impedance and cycle performance（EIS） test.Results show that the introduction of Mo source to generate MoO_3 and in situ generation of TiO_2 to modificate the materials could increase the contact area of electrolyte and electrode materials and form ion channel,speed up the rate of electrolyte ions moving rate,so as to improve the electrochemical properties.
