In this paper, TiO2 nanotubes were synthesized electrochemically by anodization of pure Ti sheet in 0.5% HF and annealed in N2 atmosphere to obtain (TONTs-N2) then the platinum was deposited on the support TONTs-N2 by chemical deposition method using NaBH4 as reducing agents to obtain the electrocatalyst Pt-B/TONTs-N2. The physicochemical characterizations of Pt-B/TONTs-N2 were performed by scanning electron microscopy (SEM), X-ray diffraction (XRD analysis). The catalyst Pt-B/TONTs-N2 was electrochemically characterized in basic solution of methanol by cyclic voltammetry (CV) measurement. XRD characterization indicates the presence of platinum nanoparticles with diameter less than 54.8 nm and regularly combined into TiO2 nanotubes. Pt-B/TONTs-N2 catalyst exhibited a remarkably high electrocatalytic activity and has high electrocatalytic stability for methanol electrocatalytic oxidation reaction. In addition, the Pt-B/TONTs-N2 catalyst exhibits better poison tolerance and higher methanol oxidation current density than that reported for Pt/carbon catalyst. This suggests that the Pt-B/TONTs-N2 catalyst supported on TONTs-N2 has promising potential applications in electro catalyst reactions. Pt supported on the conductive support TONTs-N2 is used as electrocatalyst in alkaline fuel cells. Results showed best improvement in physico-chemical properties of these catalysts in comparison with previous studies. |
