A novel well-dispersed Pd@HHSS catalyst was synthesized by reduction of Pd(OAc) immobilized on HHSS we reported. When the ratios of Pd/SiO were 5 : 100 and 10 : 100, the Pd nanoparticles size was about 5-10 nm. The Pd@HHSS catalyst (Pd/SiO = 10 : 100) showed high catalytic activity in Suzuki-reaction with yields of 91-99% and the catalyst is reusable after four successive cycles without obvious loss of catalytic activity.
我们报道了一种通过还原固定在HHSS上的Pd(OAc)合成的新型均匀分散的Pd@HHSS催化剂。当Pd/SiO的比例为5:100和10:100时，钯纳米颗粒的尺寸约为5-10纳米。Pd@HHSS催化剂（Pd/SiO = 10:100）在铃木反应中表现出高催化活性，产率为91-99%，并且该催化剂在连续四个循环后可重复使用，催化活性没有明显损失。
