Abstract | Ni-Fe layered double hydroxide (LDH) nanosheets and hierarchical Ni-Fe LDH@MnO2 spheres are synthesized by a facile and cost-effective approach for highly efficient ethanol electro-oxidation. The LDH@MnO2 microspheres display excellent catalytic activity and robust durability for ethanol electro-oxidation, compared with the Ni-Fe LDH nanosheets. According to the analyses for nitrogen adsorption isotherms and electrochemical impedance spectra (EIS), it is inferred that the performance enhancement could be attributed to the MnO2 increasing the concentration of OHads species on the Ni-Fe LDH surface. These OHads can react with C-1ad intermediate species to produce CO2 or water soluble products, releasing the active sites on LDH for further electrochemical reactions. Therefore, it is expected that an effective noble-metal free catalyst for ethanol electro-oxidation could be obtained by tailoring structure and properties of LDHs and their composites. |
