摘要：

Carbon modified TiOnanobelts(TiO-C) were synthesized using a hydrothermal growth method,as a support material for palladium(Pd) nanoparticles(Pd/TiO-C) to improve the electrocatalytic performance for methanol electrooxidation by comparison to Pd nanoparticles on bare TiOnanobelts(Pd/TiO)and activated carbon(Pd/AC). Cyclic voltammetry characterization was conducted with respect to saturated calomel electrode(SCE) in an alkaline methanol solution, and the results indicate that the specific activity of Pd/TiO-C is 2.2 times that of Pd/AC and 1.5 times that of Pd/TiO. Chronoamperometry results revealed that the TiO-C support was comparable in stability to activated carbon, but possesses an enhanced current density for methanol oxidation at a potential of -0.2 V vs. SCE. The current study demonstrates the potential of Pd nanoparticle loaded on hierarchical TiO-C nanobelts for electrocatalytic applications such as fuel cells and batteries.
