摘要
以腐植酸为原料,通过简单的方法制得了腐植酸负载Pd(HA-Pd)和腐植酸负载Pd/Ni催化剂(HA-Pd/Ni).用NaBH4作为还原剂,得到腐植酸负载Pd和腐植酸负载Pd/Ni催化剂的还原产物(HA-Pd(0)和HA-Pd/Ni(0)).研究了腐植酸负载Pd和腐植酸负载Pd/Ni催化剂及其还原产物对芳基卤与乙烯基化合物的Heck反应的催化性能.结果显示,该类催化剂均能够很好地催化溴苯与丙烯酸的Heck芳基化反应.
Two catalysts, HA-Pd and HA-Pd/Ni, were prepared readily from humic acid. The reducing products of HA-Pd and HA-Pd/Ni were synthesized by using NaBH4. The catalytic performances of the four catalysts, HA-Pd, HA-Pd/Ni and their reducing products were studied by Heck reaction. The results showed that the four catalysts all could catalyze Heck reaction of bromobenzene with acrylic acid.
