文摘

SnO₂ and SnO₂@C have been successfully synthesized with a simple hydrothermal procedure combined with heat treatment, and their performance as cathode catalysts of Li-air batteries has been comparatively evaluated and discussed. The results show that both SnO₂ and SnO₂@C are capable of catalyzing oxygen reduction reactions (ORR) and oxygen evolution reactions (OER) at the cathode of Li-air batteries, but the battery with SnO₂@C displays better performance due to its unique higher conductivity, larger surface area, complex pore distribution, and huge internal space.
