Coordination and interface engineering to boost catalytic property of two-dimensional ZIFs for wearable Zn-air batteries
文献摘要：
Metal organic frameworks(MOFs)have been considered as compelling precursor for miscellaneous appli-cations.However,their unsatisfied electrocatalytic performance limits their direct application as electro-catalyst.Herein,by incorporating the cobalt-oxide bonds and polyaniline(PANI)with two-dimension zeolitic imidazolate frameworks(ZIFs),a novel bifunctional catalyst(Co-O-ZIF/PANI)for Zn-air battery was designed based on a facile and eco-friendly method.This Co-O-ZIF/PANI with optimized surface adsorption effect and suitable Co3+/Co2+ratio,exhibits eminent electrocatalytic activity toward both oxy-gen reduction and evolution reaction.The as-assembled liquid ZABs based on Co-O-ZIF/PANI achieves a remarkable maximum power density of 123.1 mW cm-2 and low discharge-charge voltage gap of 0.81 V at 5 mA cm-2 for over 300 cycles.Operando Raman spectroscopy reveals that the excellent performance origins from the optimized surface chemisorption property of O2 and H2O brought by Co-O bonds and PANI.This work provides a novel prospect to develop efficient MOF derived bifunctional electrocatalysts by optimizing surface chemisorption properties.
