主讲人简介

Lin Guo received his B.S. degree from Northeast Normal University in 1985, M.S. degree from Jilin University in 1992, and Ph.D. degree from Beijing Institute of Technology in 1997. In 2001, he was appointed as one of the first President-Appointed Professors at Beihang University. He is currently a Professor at the School of Chemistry, Deputy Director of the State Key Laboratory of Biomimetic Interfacial Materials Science, Principal Investigator of a Major Program of the National Natural Science Foundation of China, and Chief Scientist of the National Key R&D Program of the Ministry of Science and Technology. He is a recipient of the State Council Special Government Allowance. He has long been engaged in the synthesis and properties of inorganic amorphous micro/nanomaterials. In response to major national demands in the aerospace field, he has established a systematic chemical synthetic methodology for amorphous micro/nanomaterials and the associated theory of structure-property relationships. As the first completer, he was awarded one Second Prize of the National Natural Science Award, as well as the First Prize of the Natural Science Award of the Ministry of Education, the Baosteel Excellent Teacher Award, Beijing Excellent Teacher Award, Beijing Outstanding Supervisor of Graduate Students, National Excellent Doctoral Dissertation Supervisor Award, and National Excellent Teacher Award, among other honors. He received the National Science Fund for Distinguished Young Scholars in 2007, was selected into the National Hundreds, Thousands, and Ten Thousands Talent Program in 2009, was appointed as a Distinguished Professor of the Changjiang Scholars Program of the Ministry of Education in 2011, and was elected as an Academician of the Chinese Academy of Sciences in 2025.

讲座简介

The unique structure of amorphous micro/nanomaterials endows them with distinctive advantages and significant theoretical research implications in the fields of catalysis, mechanics, and human health. The poor controllability in the synthesis and the difficulty in structural characterization of amorphous nanomaterials have hindered the understanding and establishment of effective structure-property relationships, severely constraining the development and application of amorphous nanomaterial research. The research team has developed a variety of universal methodologies, including coordination competition, spatial confinement, ligand induction, and in situ transformation strategies, enabling the controlled synthesis of amorphous nanomaterials with tunable morphology, size, and dimensionality. A new direction has been pioneered for the efficient activation of N2 and CO2 by creating amorphous nanocatalysts through amorphization and heteroion coupling to regulate the p-orbital electronic states of main-group elements and the f-orbital electronic states of rare-earth elements. The catalytic, mechanical, optical, and dental restorative properties as well as potential applications of the materials have been systematically investigated, with the underlying mechanisms proposed and scientific structure-property relationships established, thereby advancing both the fundamental research and practical applications of amorphous micro/nanomaterials.
