Revolutionary nanocomposite material of CrO4-ZrO2 prepared by using a simple technique of coprecipitation and sonication. Prepared HR-SEM materials characterized with an EDX, HR-TEM, XRD, PL and UV-Vis DRS analysis. HR-SEM images demonstrate the prepared materials shown in spherical multi shaped chain structure. (EDX) analysis ensures the nanocomposite material presents of Cr, Zr and O. Analysis of X-ray diffraction studies shows that the synthesized material monoclinic in nature. The PL analysis and UV–Vis DRS analysis were very useful to explain catalytic activity of synthesized particles. This material nanocomposite increases Trypan Blue (TB) dye concentration photocatalytic activity of 1x10-4 solution at pH 7 Optimal CuO nanomatter. For higher CrO4-ZrO2 activity than ZrO2, a possible mechanism is proposed for 365 nm under UV radiation. DSSCS analysis showed improved current output, short circuit industrial electrochemical application of CrO4-ZrO2 nanocomposite material and prepared CrO4-ZrO2 nanocomposite material to be stable and reusable to be concluded with electrochemical properties of synthetic colouration and natural dye.
