摘要:
以N异丙基丙烯酰胺(NIPAAm)和4乙烯基三苯基膦(DPPS)为单体,偶氮二异丁腈(AIBN)为引发剂,通过溶液自由基聚合制备温敏聚合物P(NIPAAm co DPPS);然后将醋酸钯引入到P(NIPAAm co DPPS),并加入NaBH4还原,可得到温敏聚合物负载钯催化剂P(NIPAAm co DPPS)Pd(0)。通过调控NIPAAm与DPPS的摩尔投料比,可得到一系列不同转变温度的温敏聚合物;利用1H NMR、 31P NMR、GPC对温敏聚合物的结构进行表征,利用 31P NMR、XRD和TEM对所得催化剂进行表征,并通过TG对Pd含量进行分析;以水相中对硝基苯酚(4NP)的还原为模型反应,研究温度、催化剂用量以及循环使用次数对催化性能的影响。结果表明:P(NIPAAm co DPPS)Pd(0)中Pd纳米粒子具有良好的分散性且含量为2 8 wt%;当温度低于其转变温度时该催化剂具有较高的催化活性,转化率较高,且在循环使用10次后,转化率仍保持在98%,而当温度高于其转变温度时转化率显著降低。
