将科研课题“聚苯胺负载纳米金催化剂的制备及其催化性能研究”设计成应用化学专业综合实验，将科研课题的创新性和教学可行性有机结合，以推进创新型人才的培养。实验以苯胺单体（ANI）为原料，以过硫酸铵（APS）为氧化剂，制备聚苯胺（PANI）载体。采用金胶负载法、PANI原位还原法、ANI原位还原法三种载金方式分别制备PANI负载纳米金催化剂，并以NaBH₄存在条件下，对硝基酚（4-NP）还原制备对氨基酚反应（4-AP）为探针评价催化剂的催化性能。实验内容多学科交叉融合，涉及催化剂的制备、催化剂的结构表征、催化剂的活性评价等多种内容。通过本次实验，学生可以经历催化学科科学研究的全过程，掌握催化材料的制备方法，并熟练运用红外光谱（FT-IR）、紫外光谱（UV-Vis）、X射线衍射光谱（XRD）等大型设备对所制备催化材料进行分析，进而激发学生的学习兴趣，提高学生的科研素养。
