摘要
以水溶剂中Ullmann反应为目标反应,设计具有纳米介孔结构的Pd/MCM-41作为其高效催化剂.与传统SiO2载体负载的Pd催化剂比较,该催化剂在以水为介质的碘苯偶合(Ullmann反应)中显示出优良的催化活性和对联苯的选择性.
Pd/MCM-41 catalyst was used as a catalyst for the Ullmann coupling reaction carried out in aqueous solution, which is an important researching topic for green chemistry. The Pd/MCM-41 showed higher catalytic activity and even better selectivity in comparison with the traditional catalysts, such as Pd/SiO2 and Pd/C. Based on characterizations, the correlation of the catalytic properties to the catalyst structure were discussed briefly.
