摘要
固体催化剂的合成、表征和应用是多相催化技术的核心内容,但其合成周期长、表征所需大型仪器众多,因此在本科教学实验中难以实际开展。依托大连理工大学科研课题,以ZSM-5分子筛为研究对象,采用虚拟仿真技术,通过19步的人机互动实现了催化剂合成、表征及催化性能评价全过程。教学实践表明,虚拟实验对真实实验的模拟可以有效解决本科生在多相催化领域的核心技术和研究方法等方面能力缺失问题,加深学生对理论知识的理解,提高学生的学习兴趣,培养学生的自主创新能力。
The synthesis,characterization and application of solid catalysts are the core content of heterogeneous catalysis technology.However,the synthesis cycle of solid catalysts is long and many large-scale instruments are needed for characterization,so it is difficult to carry out the actual experiments in undergraduate teaching.Based on the research project of Dalian University of Technology,and by taking ZSM-5 molecular sieve as the research object,the whole process of catalyst synthesis,characterization and catalytic performance evaluation is realized through 19 steps of human-computer interaction by using virtual simulation technology.Teaching practice shows that the simulation of virtual experiment to real experiment can effectively solve the problem of undergraduates’lack of ability in the core technology and research methods in the field of heterogeneous catalysis,deepen their understanding of theoretical knowledge,improve their interest in learning,and cultivate their ability of independent innovation.
