摘　　要：设计了不同晶粒尺寸的Ni纳米粒子催化剂及其制备生物燃料的综合化学实验。通过常规浸渍法制备了Ni/CeO_(2)、Ni/CeO_(2)-SiO_(2)和Ni/SiO_(2)三种纳米催化材料,借助X射线粉末衍射(XRD),X射线光电子能谱(XPS)和透射电子显微镜(TEM)等对其进行了物理化学性质表征。通过参与催化剂合成、结构表征及其性能评价的全链条科研基本训练过程,不仅能够培养学生的综合实验技能,还能提升其科研素养,启发学生发现物质结构与性能之间内在规律,激发学生对探索未知科学领域的兴趣。该实验以“能源危机”为话题开展课程思政,加强学生对我国能源与环境危机现状的认识,引导学生从自我做起爱护环境。This study outlines the design of a comprehensive chemical experiment to synthesize Ni-based nanocatalysts with varying grain sizes for biofuel production.Ni/CeO_(2)、Ni/CeO_(2)-SiO_(2) and Ni/SiO_(2) nanomaterials were prepared via a conventional impregnation method and characterized by X-ray diffraction(XRD),X-ray photoelectron spectroscopy(XPS),and transmission electron microscopy(TEM).The integrated scientific training process—from catalyst synthesis and structural characterization to performance evaluation—not only cultivate students’comprehensive experimental skills,but also enhance their research literacy.This experiment aims to illuminate the intrinsic relationship between material structure and function,fostering a curiosity for investigating the unknown in the scientific realm.Moreover,the experiment incorporates a curricular focus on the“energy crisis”,heightening students’awareness of current energy and environmental challenges,and inspiring a personal commitment to environmental stewardship.
