SiO2负载天然生物高分子材料壳聚糖(简写为CS),再络合FeCl3,所得催化剂SiO2-CS-FeCl3,利用高分子载体对催化活性物种的保护和Fe-Ni双金属协同效应,在催化硝基苯及其衍生物的还原羰化反应中表现出了较高的催化活性和选择性.
A silica-supported chitosan-iron complex SiO2-CS-FeCl3 has a good conversion for reductive carbonylation of nitrobenzene.The high activity and selectivity of the catalyst have been achieved by the synergic effect of Fe-Ni bimetallic system and the effect of polymer protection.
