MnO_(2)-C载体对Pd催化剂电催化性能的研究

Study on effect of MnO_(2)-C mixed support on electrocatalytic oxidation performance of Pd catalyst in formic acid

以MnO_(2)和CabotVulcanXC-72为原料合成了MnO_(2)-C材料,并将其用作担载Pd纳米颗粒的载体,从而制备出Pd/MnO_(2)-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MnO_(2)在载体材料中所占比例,当MnO_(2)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。

MnO_(2)-C material was synthesized from MnO_(2)and Cabot Vulcan XC-72 and used as a carrier to support Pd nanoparticles to prepare Pd/MnO_(2)-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 MnO_(2)in the carrier material,When MnO_(2)accounts for 15%of the mass of the support,the stability and activity of the catalyst in formic acid reach the highest.
