【摘要】 文中合成了金属氧化物（Mn₃O₄、MoO₃和SnO）掺杂的Pd基催化剂,研究了其催化甲醛氧化（formaldehyde oxidation reaction,FOR）的能力。结果表明,Pd-Mn₃O₄展示出最高的FOR活性（3.5 mA/cm²）,是纯Pd催化剂的2.6倍。以Pd-Mn₃O₄为工作电极敏感材料的甲醛传感器对甲醛的响应是干扰气体的20倍,显示出良好的气体选择性。Pd-Mn₃O₄传感器在甲醛检测方面显示出巨大应用潜力。更多还原

【Abstract】 In this article,Pd based catalysts doped with metal oxides（ Mn₃O₄,MoO₃ and SnO） were synthesized and catalyticformaldehyde oxidation reaction（ FOR） performance was studied.The results demonstrated that the Pd-Mn₃O₄ catalyst exhibited the highest FOR activity（ 3.5 mA/cm²）,which is 2.6 times of pure Pd catalysts.The response of the formaldehyde sensor using Pd-Mn₃O₄ as the working electrode sensitive material to formaldehyde is 20 times that of the interfering gas,showing good gas selectivity.The Pd-Mn₃O₄ sensor shows great potential in formaldehyde detection.更多还原
