And the pentavalent vanadium ions can be subjected to multi-step reduction in the charging and discharging processes, so that higher energy density is provided. In addition, as a member of the copper vanadate system, Cu3(VO4)2The forbidden band width of the semiconductor material is about 2.0eV, so that the semiconductor material can generate photon-generated carriers under the irradiation of visible light, and the semiconductor material is a semiconductor material with great application potential. Cu3(VO4)2The first natural minerals found in crater have been reported to be less synthetic.

Besides, there are few reports. Taking materials with similar structures as examples, the preparation of starfish Ni by a solvothermal method and dodecyl trimethyl ammonium bromide as a morphology control agent3(VO4)2[Chang B,Zhao G,Shao Y,et al.Photo-enhanced electrocatalysis of sea-urchin shaped Ni3(VO4)2for the hydrogen evolution reaction[J].Journal of Materials Chemistry A,2017,5,18038-18043.]. The preparation of large-scale single crystal Ba by a solid phase method3(VO4)2[ high-mega-even, Zhao bin, Chen Zhong3(VO4)2Production of crystalsInvestigation of Long and Raman Properties [ J]The intraocular lens study, 2008(05), 1079-.]. Preparing Zn by magnetron sputtering and hydrothermal method3(VO4)2[Mukhtar S,Zou C,Wei G.Zn3(VO4)2prepared by magnetron sputtering:microstructure and optical property[J].Applied Nanoscience,2013,3(6):535-542.Ni S,Wang X,Guo Z,et al.Crystallized Zn3(VO4)2:Synthesis,characterization and optical property[J].Journal of Alloys and Compounds,2010,491(1):378-381.].

Magnetron sputtering requires special equipment and can only be used for film production. Hydrothermal method also has the disadvantages of more control variables, the need of surfactant for regulating morphology and the use of high-pressure reaction kettle as a reactor.
