Fe 3 O 4磁性纳米颗粒(MNP)通过(3-氨基丙基)三乙氧基硅烷进行硅烷化改性。原子转移自由基聚合引发位点固定在胺官能化的Fe 3 O 4 MNP上。然后在Fe 3 O 4 -SiO 2 -Br纳米粒子存在下进行了4-乙烯基吡啶的表面引发的原子转移自由基聚合,这导致形成Fe 3 O 4 -SiO 2 -P4VP [P4VP = poly( 4-乙烯基吡啶)]与Fe 3 O 4交联的杂化微凝胶MNP。我们的方法使用聚合物微凝胶作为模板,用于合成镍纳米粒子(NiNPs)。合成的NiNPs @ Fe 3 O 4 -SiO 2 -P4VP pH敏感微凝胶的可调性质用于脂肪族和芳香族腈的催化还原。而且,已经评估了可以通过改变pH值的微凝胶结构的体积转变来调节的金属纳米复合材料的催化活性。使用TEM,X射线光电子能谱,热重分析,原子吸收光谱,XRD,UV / Vis光谱和FTIR光谱来表征所得的催化剂。
