摘要：

Different from the conventional Zinc-Air batteries which only involves oxygen reduction and evolution (ORR/ OER) in the cathode, the cathode of rechargeable zinc-air/iodide hybrid batteries (ZAIHBs), with the addition of I- species, involves I- electrooxidation (IOR) during charging and oxygen/iodate reduction (ORR and IDR) during discharging. This work reports the synthesis of a hierarchically porous tungsten-based nitrogen-doped carbon framework (W/N/C) with abundant WNx active sites and numerous ultrafine WN nanoclusters and explores their application as a trifunctional IOR/ORR/IDR electroc...
