Abstract:
We report a wire-shaped bifunctional oxygen photoelectrode by integrating Li-doped TiO2 nanotubes and Pt nanoclusters. Conductive nanoshells have been identified at the lithiated interface of Pt/TiO2, which facilitates the performance of oxygen catalysis. Thus, the assembled Zn-air micro-battery with solar-assisted charging greatly improves the voltage efficiency compared with the conventional state-of-the-art catalyst as the air electrode.
