Partial deposition of carbon onto mesoporous TiO2 (C/TiO2) 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 TiO2 fibers provided excellent electrical conductivity and strong interfacial interaction between TiO2 support and Pt metal nanoparticles. Methanol oxidation reaction results showed that the activity of Pt-C/TiO2 is 3.0 and 1.5 times higher than that of Pt-TiO2 and Pt-C, respectively. In addition, the Pt-C/TiO2 exhibited a 6.7 times enhanced stability compared with Pt-C after 2000 cycles. The synergistic effect of C/TiO2 is responsible for the enhanced activity of Pt-C/TiO2, and its excellent durability could be ascribed to the strong interfacial interaction between Pt nanoparticles and C/TiO2 support.

Pt-C/TiO 2 甲醇氧化的优异性能：介孔和部分包覆碳的贡献

碳在介孔 TiO2 (C/TiO2) 上的部分沉积被制备为用于 Pt 催化剂开发的支撑基材。碳沉积是通过糠醇的原位碳化实现的。混合催化剂通过XRD、Raman、SEM和TEM表征，在甲醇氧化反应中表现出优异的催化活性和稳定性。涂覆在介孔 TiO2 纤维上的异质碳提供了优异的导电性和 TiO2 载体和 Pt 金属纳米颗粒之间的强界面相互作用。甲醇氧化反应结果表明，Pt-C/TiO2 的活性分别是 Pt-TiO2 和 Pt-C 的 3.0 倍和 1.5 倍。此外，在 2000 次循环后，Pt-C/TiO2 的稳定性比 Pt-C 提高了 6.7 倍。
