A 12-vanadotungstate-based imidazole hybrid compound (C3H5N2) 4 [VW12O40] · 1.25H2O was prepared by hydrothermal synthesis method and its structure was characterized by IR, UV and X-ray single crystal diffraction. The analytical results show that the crystal belongs to the triclinic system, space group P1-, which is composed of [VW12O40] 4-cluster anion, protonated imidazole and crystal water. The title compound was made into a carbon paste electrode. Anping studied its electrochemical behavior and its electrocatalytic activity for NO2-reduction. Rhodamine B was used as a mimic to explore the photocatalytic activity of the compound. The results show that the use of the title compound modified carbon paste electrode NO2- Of the reduction has good electrocatalytic activity; the title compound as a photocatalyst in degradation of Rhodamine B reaction has good visible light catalytic activity.
