Abstract

Partial deposition of carbon onto mesoporous TiO ₂ (C/TiO ₂ ) were prepared as supporting substrate for Pt catalyst development. Carbon deposition is achieved by in-situ carbonization of furfuryl alcohol. The hybrid catalysts were characterized by XRD, Raman, SEM and TEM and exhibited outstanding catalytic activity and stability in methanol oxidation reaction. The heterogeneous carbon coated on mesoporous TiO ₂ fibers provided excellent electrical conductivity and strong interfacial interaction between TiO ₂ support and Pt metal nanoparticles. Methanol oxidation reaction results showed that the activity of Pt-C/TiO ₂ is 3.0 and 1.5 times higher than that of Pt-TiO ₂ and Pt-C, respectively. In addition, the Pt-C/TiO ₂ exhibited a 6.7 times enhanced stability compared with Pt-C after 2000 cycles. The synergistic effect of C/TiO ₂ is responsible for the enhanced activity of Pt-C/TiO ₂ , and its excellent durability could be ascribed to the strong interfacial interaction between Pt nanoparticles and C/TiO ₂ support.
