Synthesis of NiO/TiO2 sub-microrods as catalyst for methanol oxidation reaction
[Formula: see text] sub-microrods have been synthesized via a simple two-step route. First, the precursors were prepared by a facile ethylene glycol-mediated method; then, [Formula: see text] sub-microrods were obtained by a limited-oxygen atmosphere deriving from the decomposition of urea at [Formula: see text]C for 3 h in air. The samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS) and transmission electron microscopy (TEM). The obtained [Formula: see text] sub-microrods exhibit cubic NiO structure with high crystallinity and anatase [Formula: see text]. Both SEM and TEM show the typical sub-microrods with lengths of [Formula: see text] nm and diameters of [Formula: see text] nm. The uniform sub-microrods have great electrocatalytic performance for methanol oxidation reaction in alkaline solution. This material may have potential applications in direct methanol fuel cells.
