【摘要】 以MnO₂和Cabot Vulcan XC-72为原料合成了MnO₂-C材料，并将其用作担载Pd纳米颗粒的载体，从而制备出Pd/MnO₂-C催化剂，并研究其在酸性环境下对甲酸的电催化氧化性能，在电化学测试中，催化剂的稳定性及活性有明显的提高，通过进一步的优化MnO₂在载体材料中所占比例，当MnO₂占载体质量15%时，催化剂在甲酸中氧化的稳定性及活性达到最高。更多还原

【Abstract】 MnO₂-C material was synthesized from MnO₂ and Cabot Vulcan XC-72 and used as a carrier to support Pd nanoparticles to prepare Pd/MnO₂-C catalyst.Its electrocatalytic oxidation performance for formic acid environment was studied.In electrochemical test, the stability and activity of the catalyst were significantly improved.By further optimizing the proportion of MnO₂ in the carrier material, When MnO₂ accounts for 15% of the mass of the support, the stability and activity of the catalyst in formic acid reach the highest.更多还原
