Abstract

Abstract: Due to the high swelling capacity and large surface area, montmorillonite (MMT) has been proven a good platform for the fabrication of efficient oxygen reduction reaction (ORR) catalysts. In this work, the composite of CoFe layered double hydroxide (CoFe-LDH), graphene oxide (GO) and MMT was synthesized via a facile co-precipitation method. The characterization with X-ray diffraction spectroscopy (XRD) and scanning electron microscopy (SEM) indicates that the prepared FeCo-LDH/GO@MMT contains no impurities and exhibits a hierarchical flower-like microstructure. Further investigation shows that FeCo-LDH/GO@MMT possesses excellent ORR activity with 4e-route selectivity, suggesting the synergistic effect between CoFe-LDH, GO and MMT.
