On the morning of September 8, 2025, at the invitation of Professor Tang Yuxin from the School of Chemical Engineering of our university, Professor Zhang Yongqi from the University of Electronic Science and Technology of China and Professor Xia Xinhui from Zhejiang University of Technology delivered wonderful online academic reports to teachers and students.
1. Professor Tang Yuxin from the School of Chemical Engineering of our university gave an academic report titled "Preparation of Nano-Functional Materials Driven by Plasma Technology".
As the fourth state of matter, plasma possesses high reaction activity and a unique energy state, enabling material synthesis and structural regulation that are difficult to achieve through traditional methods under mild conditions. Researcher Zhang's team has developed a set of high-efficiency radio frequency plasma technology, which realizes precise deposition, phase transition, and surface modification of new energy electrode materials, and has made multiple breakthroughs in defect engineering and nanostructure construction. This technology has a wide range of applicable sources—gaseous, liquid, and solid precursors can all participate in plasma reactions—significantly expanding process adaptability.
By using nitrogen plasma treatment, Researcher Zhang Yongqi's team efficiently converts metals and metal oxides into corresponding nitrides within a time scale of milliseconds to seconds. Moreover, through parameter regulation, they achieve directional etching of three-dimensional porous structures or effective preservation of the original morphology. In addition, with solids such as urea, thiourea, and ammonium fluoride as plasma sources, the team has successfully prepared nitride carbon coating layers, nitrogen-sulfur co-doped dual-phase metal compounds, and nitrogen-fluorine co-doped electrode materials. They have also systematically revealed the regulatory mechanism of heterogeneous element doping on electrocatalytic performance. Furthermore, the team has developed carbon-supported sub-nano metal electrode materials using metal salts as precursors, which exhibit excellent performance in multiple electrocatalytic reactions.
In terms of characterization and mechanism research, Researcher Zhang Yongqi's team employs in-situ spectroscopy and microscopy techniques to track in real time the structural evolution of materials and the migration behavior of elements during plasma reactions. This provides key experimental evidence for understanding the interaction between plasma and materials. Multiple results show that this technology can achieve efficient preparation and modification of electrode materials at the near-atomic scale, demonstrating good scalability and application potential.
Centering on his own scientific research practice, Researcher Zhang Yongqi vividly expounded the complete innovation path from the discovery of basic problems to the integration of technical solutions. His interdisciplinary research methods brought profound inspiration to the teachers and students present. This report effectively promoted the interdisciplinary integration and innovative cooperation in the fields of materials science, physics, chemistry, and other disciplines.

2. Professor Xia Xinhui from Zhejiang University of Technology gave an academic report titled "Plasma Technology and Its Application in Battery Materials".
As a material state with high reactivity and diverse functions, plasma technology has attracted considerable attention in the field of energy materials in recent years. Professor Xia Xinhui focused on introducing the development progress of radio frequency plasma process equipment and its multiple application practices in battery materials. These applications cover cutting-edge directions such as interface modification of secondary battery materials—including plasma interface regulation of metal anodes (lithium, sodium, etc.), low-temperature carbon coating of cathode materials, doping functional modification of electrode materials, as well as the synthesis and structural optimization of new battery carbon materials.
Following the thread of his own scientific research experience, Professor Xia Xinhui vividly recounted the complete innovation chain from the identification of scientific issues to the implementation of technology integration. His interdisciplinary and integrated innovation research model provided rich insights for the teachers and students present. This report effectively promoted in-depth communication and collaborative innovation among multiple disciplines such as materials science, physics, and chemistry.
