Summary
Because of the excessive swelling capability and huge floor space, montmorillonite (MMT) has been confirmed a superb platform for the fabrication of environment friendly oxygen discount response (ORR) catalysts. On this work, the composite of CoFe layered double hydroxide (CoFe-LDH), graphene oxide (GO) and MMT was synthesized through a facile co-precipitation technique. The characterization with X-ray diffraction spectroscopy (XRD) and scanning electron microscopy (SEM) signifies that the ready FeCo-LDH/GO@MMT accommodates no impurities and displays a hierarchical flower-like microstructure. Additional investigation reveals that FeCo-LDH/GO@MMT possesses glorious ORR exercise with 4e-route selectivity, suggesting the synergistic impact between CoFe-LDH, GO and MMT.
