TiO2 - C纳米复合材料负载钯催化剂的制备及其对甲酸的电催化氧化

Preparation of TiO2 - C Nanocomposites Supported Pd Catalyst and Their Electrocatalytic Activities for Formic Acid Oxidation

    摘要
  • 摘要: 通过将TiO2 和三聚氰胺的混合物高温煅烧制备出纳米复合材料，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5 nm，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

     

    Abstract: 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 as-prepared 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
