Highly active catalysts for the methanol steam reforming (MSR) capable of operating efficiently at the same temperature of high temperature polymer electrolyte membrane fuel cells (HTPMFCs) devices are strongly desired. A novel CuO/ZnO/Ga₂O₃ catalyst was synthesized by co-precipitation method and characterized by ICP-AES, N₂-physisorption, SEM-EDX and XRD. This catalyst showed a catalytic activity 2.2 times higher than commercial CuO/ZnO/Al₂O₃ catalysts at 453 K Two kinetic models one empirical and one mechanistic were applied to describe the methanol steam reforming reaction over one of the most promising catalyst family.

低温MSR反应的CuO / ZnO / Ga ₂ O ₃催化剂：合成，表征和动力学模型

迫切需要能够在高温聚合物电解质膜燃料电池（HTPMFCs）装置的相同温度下有效运行的甲醇蒸汽重整（MSR）的高活性催化剂。通过共沉淀法合成了新型的CuO / ZnO / Ga ₂ O ₃催化剂，并通过ICP-AES，N _2-物理吸附，SEM-EDX和XRD对其进行了表征。该催化剂在453 K时的催化活性比市售CuO / ZnO / Al ₂ O ₃催化剂高2.2倍。采用两种动力学模型（一种经验模型和一种机理）来描述甲醇蒸汽重整反应是最有前景的催化剂家族之一。
