On the evening of June 24, the 2020 graduate tutor exchange meeting and young teachers' Academic Salon of China Youth Promotion Association were successfully held in Cao Guangbiao science and technology building. The meeting was held in parallel mode of offline meeting and online live broadcast. It was presided over by Professor Jiang Yinzhu, President of the youth Promotion Association. Three researchers, Sun Wei, Fan Xiulin and Sun Wenping, gave academic reports. Deputy Secretary Zhang Shiliang and more than 200 teachers and students participated in the discussion and exchange.

At the beginning of the conference, Deputy Secretary Zhang Shiliang stressed the important role of new material technology in the two overall situations of unprecedented changes in the world and the great rejuvenation of the Chinese nation. He encouraged young teachers and material students to carry forward the spirit of Zhejiang University, grasp the development opportunities and challenges of an innovative country, and make continuous efforts to seize the commanding heights of new materials and build a material power, We hope to provide a better platform for the exchange and cooperation between young teachers and materials students.

Then, Researcher Sun Wei made a report entitled nano silicon-based CO2 photo thermal catalytic materials, pointing out that silicon materials as traditional photoelectric materials have the advantages of low price, high abundance, low toxicity and strong light absorption, and their huge industrial scale tends to radiate to energy, catalysis, environment and other fields in recent years. Taking the cross field application of greenhouse gas CO2 photo thermal catalytic reduction as fuel as an example, combined with The unconventional application of nano silicon shows the characteristic strategy and performance advantages of silicon material chemistry. Prof. Sun Wenping gave a report on the surface and Interface Engineering of two-dimensional materials electrocatalyst. Starting from the development of sustainable renewable energy and efficient energy storage and conversion system, he shared the latest work on the design and research of two-dimensional nano materials through surface engineering and interface / heterostructure engineering. Professor Fan Xiulin reported the design of new electrolyte / electrolyte and its influence on the performance of high energy density batteries. He pointed out that the existing commercial EC based electrolyte could not form a stable positive electrolyte membrane and the excellent performance of Li and Si anode materials. He focused on how to adjust the electrolyte composition and design in situ on the positive and negative electrode surface to build a solid electrolyte with inorganic materials as the main component Interface layer and its principle. All the three researchers answered the questions of the teachers and students.

During the exchange and discussion, the three researchers share their years of scientific research experience and work experience without reservation. They interact closely with young teachers and students online and offline. The atmosphere is strong and the response is warm. They promote the exchange, cooperation and development among young teachers, effectively solve the students' confusion in the direction of scientific research, and expand and improve the quality of students Our scientific research vision and scientific research literacy.
