中文摘要：

通过将TiO2和三聚氰胺的混合物高温煅烧制备出TiO2-C纳米复合材料,并将其用作载体合成出Pd/TiO2-C催化剂.采用XRD,TEM,HR-TEM和EDS等手段对催化剂进行了表征分析,并考察了它们对甲酸氧化反应的催化性能.结果表明,Pd负载于碳与TiO2的界面,平均粒径为5nm,与Pd/XC-72和Pd/TiO2相比,Pd/TiO2-C催化剂具有更强的催化活性和稳定性,这归因于TiO2-C载体的特性和Pd/TiO2-C独特的异质结构.

英文摘要：

The TiO2-C hybrid material was prepared by carbonization of the mixed precursor containing TiO2 and melamine,and was used to support Pd nanoparticles for electrocatalytic formic acid oxidation.The asprepared Pd/TiO2-C catalyst was characterized by XRD,TEM,HR-TEM,EDS,and electrochemical measurements.Pd nanoparticles deposited on the hetero interfaces of TiO2-C possessed a large electrochemical surface area and exhibited enhanced activity and stability towards formic acid oxidation.
