中文摘要：

为进一步克服常规一氧化碳催化偶联反应的技术性不足,作者课题组在热催化反应的基础上探索性引入了人工光源,通过光催化和热催化对一氧化碳偶联反应的共同作用,降低反应温度并提高产品的收率和选择性。我们采用浸渍法制备了负载量为1%的二氧化钛-氧化铝负载的钯催化剂Pd-TiO2/Al2O3,并将该催化剂用于光-热气相催化一氧化碳与亚硝酸甲酯偶联生成草酸二甲酯/碳酸二甲酯。研究证明在60～110℃时,引入的人工光源能够将主要产物草酸二甲酯的产率提高20%～50%,选择性提高10%～30%,表明在一氧化碳偶联反应中,光-热协同催化效应能够有效提高催化剂的反应活性,同时调控产物的选择性。相关协同催化机理的研究目前正在展开中。
