由醇-水溶液加热法结合超临界流体干燥制备得到晶体结构完整、磁性良好、比表面积大的NiFe2O4并用其作为载体，通过简单的浸渍法制备NHC-Pd/NiFe2O4催化剂.NHC-Pd/NiFe2O4催化Suzuki反应表现出高活性和高循环稳定性.催化剂五次循环后活性没有明显降低.

In this paper, we prepared NiFe2 O4 aerogels with the integrity crystal structure, good magnetic prop-erties and large surface area by the ethanol-water heating and supercritical fluid drying. Then by grafting imidazo-lium N-heterocyclic carbene palladium complex and ionic liquid on the surface of NiFe2O4, NHC-Pd / NiFe2O4 catalyst was prepared.NHC-Pd/NiFe2O4 showed high activity and significantly enhanced recyclability for the Su-zuki reactions. The catalyst could be reused for five times without remarkable decrease in activity.
