摘要

This work demonstrates the chemical deposited of nickel platinum alloy NiPt/TONs on the surface oftitanium oxides nanotubes (TONs) support pre-fabricated by anodic oxidation of Ti foil in HF solutionfollowed by annealing in air and in N2 atmosphere. The structural, surface morphology andcomposition of NiPt/TONs catalysts were characterized using X-ray diffraction (XRD), scanningelectron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS) and the inductive coupledplasma optical emission spectroscopy (ICP-OES). The electrochemical behavior and methanolcatalytic performance and stability of the NiPt/TONs catalysts were investigated by cyclicvoltammetry and compared with similar catalysts in acidic and alkaline solutions. The results indicatethat the NiPt/TONs shows higher catalytic activity for methanol electro-oxidation in both acidic andalkaline solution than that reported in the literature. This implies that TONs have promising potentialto be used as a support for catalysis applications.
