We report a wire-shaped bifunctional oxygen photoelectrode by integrating Li-doped TiO nanotubes and Pt nanoclusters. Conductive nanoshells have been identified at the lithiated interface of Pt/TiO, 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.
我们报道了一种通过整合锂掺杂的二氧化钛纳米管和铂纳米团簇制成的线状双功能氧光电极。在铂/二氧化钛的锂化界面处已识别出导电纳米壳，这有助于氧催化性能。因此，与作为空气电极的传统最先进催化剂相比，组装的具有太阳能辅助充电功能的锌空气微型电池大大提高了电压效率。
