Dual Photo-Functional Au/TiO2/NiO Nanocone Arrays Empower Flexible Zn-Urea-Air Batteries.
Photo-assisted Zn-air batteries provide an integrated route for solar energy conversion and storage, but their energy efficiency is still limited by sluggish bifunctional oxygen electrocatalysis at the air electrode. Herein, an Au nanoparticle-modified TiO2/NiO nanocone array air electrode (Au/n-TO/NiO) is developed fo...
