Abstract: Heterogeneous catalysts synthesized by conventional wet-chemistry methods, including wet-impregnation, ion exchange, and deposition-precipitation often have very complex structures along with poor uniformity of active sites. Such heterogeneity of active site structures significantly decreases catalytic performance, and hinders atomic-level understanding of structure-activity relationships. Atomic layer deposition (ALD), has emerged as an alternative method to synthesize heterogeneous catalysts from gas-phase. It relies on a sequence of molecular-level, self-limiting surface reactions between the vapors of precursor molecules and a substrate. This unique character makes it possible to deposit various catalytic materials uniformly on a high-surface-area support with nearly atomic precision, thereby providing new opportunities for bottom-up construction of catalytic architectures on a support with near atomic precision. In this talk, I will discuss three parts about (i) metal single-atom and dimeric catalysts, (ii) bimetallic catalysts and (iii) nanoscale metal-oxide engineering for establishing structure-activity relations and for advanced catalysis.

Bio: Prof. Junling Lu received his PhD degree from Institute of Physics, Chinese Academy of Sciences under the supervision of Prof. Hongjun Gao in 2007. During his PhD studies, he visited Prof. Hans-Joachim Freund group at Chemical Physics Department, Fritz-Haber-Institute, Max Planck Society as an exchange student in 2004–2006. After graduation, he spent three years in Prof. Peter C Stair’s group at Northwestern University and then about two and a half years in Dr. Jeffrey W. Elam’s group at Argonne National Laboratory as a Postdoc. In March. 2013, he became a professor at University of Science and Technology of China. His current research interest is atomically-precise design of new catalytic materials using a combined wet-chemistry and ALD approach for advanced catalysis.

Event is co-hosted by by Northwestern's Department of Chemistry and the Center for Catalysis and Surface Science (CCSS). CCSS is a strategic research center within the Institute for Sustainability and Energy at Northwestern (ISEN). CCSS promotes interdisciplinary research fundamental to the discovery and atomistically-controlled synthesis of catalysts that optimize the sustainability of industrial and consumer goods.
