•Cu3V2O8 hollow spheres were synthesized using carbon spheres as template.•Cu3V2O8 hollow spheres exhibit good photocatalytic activity.•Cu3V2O8 hollow spheres display high discharge capacity and excellent high-rate capability.
In this paper, Cu3V2O8 hollow spheres have been successfully synthesized via a liquid precipitation method with colloidal carbon spheres as template followed by a subsequent heat treatment process. On the basis of XRD analysis, SEM observation, and TG-DSC analysis of the precursor and products, the formation mechanism of Cu3V2O8 hollow spheres was proposed. UV–vis diffuse reflectance spectra showed that the Cu3V2O8 hollow spheres exhibit strong absorption in a wide wavelength range from UV to visible light. The photocatalytic activity experiment indicated that the as-prepared Cu3V2O8 hollow spheres exhibited good photocatalytic activity in degradation of methyl orange (MO) under 150-W xenon arc lamp light irradiation. Furthermore, electrochemical measurements showed that the Cu3V2O8 hollow spheres exhibited high discharge capacity and excellent high-rate capability, indicating potential cathode candidates for primary lithium batteries used in long-term implantable cardiac defibrillators (ICDs).
