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 by way of a facile co-precipitation methodology. The characterization with X-ray diffraction spectroscopy (XRD) and scanning electron microscopy (SEM) signifies that the ready FeCo-LDH/GO@MMT incorporates no impurities and displays a hierarchical flower-like microstructure. Additional investigation exhibits that FeCo-LDH/GO@MMT possesses wonderful ORR exercise with 4e-route selectivity, suggesting the synergistic impact between CoFe-LDH, GO and MMT.
