6月17日晚，我院大气污染控制及催化方向课题组的研究生同学进行了本学期第四次的学术交流活动，活动由2017级研究生陈星仡主持，到场指导的老师为徐成华老师。

交流活动中，同学们将各自在科研工作上取得的进展及遇到的困难和大家进行探讨。陈星仡同学介绍了甲醇柴油车尾气的危害以及自己在制备甲醇柴油车尾气净化催化剂的工作进展，并就实验中遇到的问题和一些想法与老师和同学们进行了讨论；候潇潇同学以《铜锰复合材料催化VOCs燃烧研究》为题，介绍了该课题的研究背景、技术方法并展示了现阶段的实验结果；郑宇皓同学以近期阅读的一篇文献为主要内容，向同学们介绍了石墨烯这一种新型材料，并对作者的实验内容、数据分析以及实验结果进行了总结和阐述；杨阳同学介绍了VOCs的来源、危害以及治理现状，并列举实际案例，分析了企业VOCs收集处理问题，提出减排措施。

本次学术交流活动展现出了浓厚的学术氛围，同学们对于自己所遇到的问题互相求助，积极探讨，对于自己所不了解的也是认真学习，提出问题，通过大家的一起探讨，提出一些解决方法，为下一步的实验提供参考思路。

最后感谢各位老师到场指导及各位同学汇报交流和到场聆听！

On the evening of June 17, the graduate students of the Air Pollution Control and Catalysis Research Group of our institute conducted the fourth academic exchange activity of this semester. The activity was hosted by the 2017 graduate student Chen Xingyi, and the teacher who was present was Xu Chenghua.

During the exchange activities, the students will discuss the progress and difficulties encountered in their research work. Chen Xingyi introduced the hazards of methanol-diesel exhaust and his work in preparing methanol-diesel exhaust gas purification catalysts. He discussed the problems encountered in the experiment and some ideas with the teachers and students. The research on the combustion of VOCs catalyzed by manganese composites introduces the research background and technical methods of the subject and shows the experimental results at the present stage. Zheng Yuhao introduced the grapheme, a new type of material to the students with a recent reading of the literature, and the author's experimental content, data analysis and experimental results were summarized and elaborated; Yang Yang introduced the source, harm and governance status of VOCs, and enumerated the actual cases, analyzed the collection and processing of enterprise VOCs, Propose emission reduction measures.

The academic exchange activities showed a strong academic atmosphere. The students asked for help from each other's problems and actively explored them. Although they did not understand what they were learning, they also carefully studied and asked questions. The method provides a reference for the next experiment.

Finally, thanks for attendance and guidance from teachers as well as each student’s report and listening.
