摘要/Abstract

摘要： 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。

Abstract: The Pd@CMP-1 catalyst, which the Pd loading contents of 1%, was first prepared by immersion and reduction method, using H₂PdCl₄ as metal precursor and CMP-1 material as a support. The catalytic hydrogenation performance of prepared catalysts was investigated using H₂ as hydrogen source and the reaction of nitro aromatic compound as probe. To study the influence of dilute nitric acid, the support was pretreatment by it. XRD, TEM and BET measurement methods were used to analyze and determine the characteristics of catalysts. The results showed that the specific surface area of Pd@CMP-1 was 720m²/g, the palladium nanoparticles could be well dispersed on it and dilute nitric acid would change the structural performance. Moreover, the effect of temperature and pressure of reaction system was investigated. It had high reactivity under the condition of 2MPa, and 100℃. It can be concluded that the Pd@CMP-1 catalyst is a high efficient and environmental friendly hydrogenation catalyst, which has excellent activity and some degree of recycle performance.
