This work reports the electrocatalytic activity of the AuCeO₂/C and Au/C catalysts toward the oxidation reaction of alcohols: methanol, ethanol, ethylene glycol, and glycerol in an alkaline medium. Gold nanoparticles (AuNPs) were deposited onto the CeO₂/C and C (carbon) substrates using the microwave irradiation method. It has been found that deposition of AuNPs onto the CeO₂/C substrate results in the enhanced electrocatalytic activity of the AuCeO₂/C catalyst toward the oxidation reaction of methanol, ethanol, ethylene glycol, and glycerol compared with that of the AuNPs deposited on the carbon substrate. The AuCeO₂/C catalyst showed up to 3 times higher electrocatalytic activity toward the oxidation of the mentioned alcohols compared with that of the Au/C catalyst.

微波辅助合成AuCeO2 / C催化剂及其在碱性介质中氧化醇的应用

这项工作报告了AuCeO ₂ / C和Au / C催化剂在碱性介质中对醇：甲醇，乙醇，乙二醇和甘油的氧化反应的电催化活性。使用微波辐射法将金纳米颗粒（AuNPs）沉积到CeO ₂ / C和C（碳）衬底上。已经发现，与沉积在AuNPs上的AuNPs相比，AuNPs在CeO ₂ / C衬底上的沉积导致AuCeO ₂ / C催化剂对甲醇，乙醇，乙二醇和甘油的氧化反应的增强的电催化活性。碳基材。AuCeO ₂与Au / C催化剂相比，/ C催化剂对上述醇的氧化显示出高达三倍的电催化活性。
