Enhanced electrocatalytic performance of mesoporous nickel-cobalt oxide electrode for methanol oxidation in alkaline solution
چکیده انگلیسی
Nickel-cobalt oxides nanocomposites with different Ni/Co ratios are fabricated by micro-wave assisted synthesis. The texture, morphology, BET surface area and electrochemical performance are found strongly related to Ni and Co concentration. The results illustrate that a hierarchical porous assembly of nanoparticles of ∼10 nm was obtained, and the ratio of Ni/Co in the nanocomposites was nearly identical to its precursors. The electro-oxidation behavior of meso-nickel-cobalt oxides outperform pure NiO and Co3O4 for methanol oxidation reaction (MOR). The Ni-Co-O nanocomposite displays a highly stable response during MOR and it considered to a favorable material to develop non-Pt based fuel cells.
