Efficient Carrier Separation via Ru@TS@C Zeolite: Enabling Photo-Cathodes for High-Efficiency Photo-Assisted Metal−Air Batteries

Neutral aqueous zinc-air batteries (ZAB) show promise for extended lifespan and recyclability compared to alkaline systems, but are hindered by limited energy efficiency and slow kinetics of power output. Recently, Ji-Jing Xu and Huan-Feng Wang from Jilin University reported an effective method for near-neutral ZABs based on photo-responsive titanium silicate molecular sieve TS-1. Key Points … Read more
