The essence of university courses lies in their scientific rigor, while the joy of learning serves as a motivating force. With this in mind, a comparative experiment was designed to investigate the catalytic role of phase configurations of two-dimensional MoS2 (2D MoS2) in maleic anhydride (MAH) selective hydrogenation to succinic anhydride (SA). This experiment was tailored for senior undergraduates majoring in energy, materials science, and chemical engineering. Through the analysis of hydrogen temperature-programmed reduction (H2-TPR), Raman, and X-ray diffraction (XRD) data, the students thoroughly explored the structural information and chemical properties of synthesized 2D MoS2. The characterization and kinetic results revealed a linear relationship between the specific reaction rate and the concentration of 1T-MoS2, affirming the superior intrinsic activity of 1T-MoS2 for MAH selective hydrogenation to SA. Following this comparative laboratory experiment, the students gained insight into the principles and processes of selective hydrogenation, learned about catalyst preparation and characterization methods, and developed scientific thinking skills for solving practical problems. Our comprehensive experiments are instrumental in enhancing students’ experimental skills and their ability to tackle practical problems using interdisciplinary knowledge.

通过二维 MoS2 在马来酸酐选择性加氢中的合成和催化应用提高本科生研究技能



大学课程的精髓在于科学严谨,而学习的乐趣则是动力。考虑到这一点,设计了一个比较实验来研究二维MoS 2 (2D MoS 2 )的相构型在马来酸酐(MAH)选择性加氢生成琥珀酸酐(SA)中的催化作用。该实验是为能源、材料科学和化学工程专业的高年级本科生量身定制的。通过氢程序升温还原(H 2 -TPR)、拉曼和X射线衍射(XRD)数据的分析,学生们深入探索了合成的2D MoS 2的结构信息和化学性质。表征和动力学结果揭示了比反应速率和1T-MoS 2浓度之间的线性关系,证实了1T-MoS 2对于MAH选择性加氢为SA具有优异的固有活性。通过本次室内对比实验,学生们深入了解了选择加氢的原理和过程,了解了催化剂的制备和表征方法,培养了解决实际问题的科学思维能力。我们的综合实验有助于提高学生的实验技能和利用跨学科知识解决实际问题的能力。
