高活性Pd/MgO催化剂的制备及其CO氧化偶联制草酸二甲酯催化反应
High active Pd/MgO catalyst for CO oxidative coupling to dimethyl oxalate
摘要
Abstract
The MgO support was first synthesized by the solution method,with which the Pd/MgO nanocatalyst was then prepared by the impregnation method.The structure and performance of prepared catalyst were characterized by XRD,CO2-TPD,BET,TG,SEM,TEM and catalytic evaluation device.The research result shows that the synthesized MgO support consists of uniform nanosheets and strong Lewis basic sites.The active Pd nanoparticles of Pd/MgO catalyst are highly dispersed on the surface of MgO support with small and homogeneous size.Moreover,the Pd/MgO nanocatalyst with a low Pd loading (0.5％) exhibits an excellent catalytic performance with 65％ CO conversion,96％ selectivity to DMO and more than 100 h on stream at 130 ℃.for CO oxidative coupling to dimethyl oxalate,much higher than industrial catalyst (Pd/α-Al2O3),which has a good prospect of industrial application.关键词
