Comparative study of the high-pressure behavior of ZnV2O6, Zn2V2O7, and Zn3V2O8

58th European High Pressure Research Group International Conference, 06/09/2020 To 11/09/2020 , Universidad de La Laguna, TenerifeVanadium oxide-based materials are currently receiving substantial attention due to their exceptional physical and chemical properties, which make them useful for many technological applications. In particular, zinc metavanadate (ZnV2O6), zinc pyrovanadate (Zn2V2O7), and zinc orthovadate (Zn3V2O8) have recently received a great deal of attention due to their proposed use in photocatalytic water splitting. These three photocatalytic materials possess favorable band-gap energies and appropriate band-edge positions for inducing the dissociation of water into its constituent parts, H2 and O2, using solar radiation. These materials also have potentials for applications as electrodes in lithium-ion batteries and supercapacitors, as phosphor for white light-emitting diodes, and as long-life cathode materials of aqueous zinc-ion batteriesThis work was supported by the Spanish Ministry of Science, Innovation and Universities under Grants MAT2016-75586-C4-1-P, PGC2018-097520-A-I00, and RED2018-102612-T (MALTA Consolider-Team), and by Generalitat Valenciana under Grant Prometeo/2018/123 (EFIMAT).
