1. 毕业设计（论文）的内容和要求

金属纳米颗粒具有较高的表面活性和大的比表面积，被广泛用作催化剂。但其属于亚稳状态，对周围环境敏感，易出现聚集状态，使催化活性降低。开发合适的载体，保证纳米颗粒的稳定性和金属分散度成为研究的热点。近年来，二维有机或金属有机材料如ZIFs材料作为一种新兴的多孔材料，由于其结构的优势而对复合催化剂的性能起到了很大的提升作用。研究发现，二维材料的GO与ZIFs材料复合可有效改善催化剂在催化过程中由于纳米颗粒聚集造成的催化性能降低的问题。本课题尝试采用原位合成法将GO和ZIF-L两种二维材料复合，并在合成过程中加入Pd活性组分，制备Pd/GO@ZIF-L催化剂，考察加入不同GO含量的二维Pd/ZG复合材料的结构对其催化性能的影响，采用XRD、FESEM、FT-IR、ICP等现代表征技术对其微结构进行表征，并以对硝基苯酚还原制备对氨基苯酚为模型反应测试其催化性能。
