Abstract:

以H2PdCl4为金属前体、共轭微孔聚合物(CMP-1)为载体,利用浸渍还原法首次合成了Pd含量为1%的负载型Pd@CMP-1加氢催化剂。以H2为氢源、硝基芳烃化合物的加氢反应为探针,对催化剂的加氢性能进行了评价。用稀HNO3对载体进行预处理,探究稀HNO3对载体的影响。并通过XRD、TEM及BET等手段对催化剂进行分析表征,结果表明Pd@CMP-1具有720m2/g的比表面积,Pd纳米颗粒均匀分散在载体CMP-1上,用稀HNO3对载体进行预处理将改变CMP-1的结构性能,不利于催化剂的制备。考察了温度和压力对反应体系的影响,实验结果表明体系在2MPa、100℃条件下具有较高的反应活性。并通过几种硝基芳烃的加氢反应可知Pd@CMP-1催化剂是一种高效环保的加氢催化剂,具有优秀的加氢性能以及一定的循环性能。
