Selective CO2 Reduction on Transition Metal Single Atom Catalysts: From Identification to Scaling-up

Department of Chemical and Biomolecular Engineering,  Rice University
Abstract: The development of highly selective and earth-abundant electrocatalysts for CO2 reduction is becoming increasingly important for renewable energy applications. The challenge here is the strong competition from water reduction, as well as the low selectivity towards a desired product. In this talk I will introduce the rational tuning of electronic properties of catalytic materials for their significantly improved CO2 reduction performance. By dispersing transition metals into isolated single atoms with electronic structures significantly different from their bulk counterparts, we can dramatically suppress the competing hydrogen evolution and deliver an ultra-high CO2 reduction selectivity of more than 95% under ambient conditions in water. Scaled-up synthesis and efficient reactors were designed for practical applications. Furthermore, with the tuning of different facet exposure on Cu catalysts, the CO2 reduction reaction pathway can be successfully shifted from C1 towards C2 or C3 high-value products.
Bio: Dr. Haotian Wang is currently a William Marsh Rice Trustee Chair Assistant Professor in the Department of Chemical and Biomolecular Engineering at Rice University. He obtained his PhD degree in the Department of Applied Physics at Stanford University in 2016 and his bachelor of science in Physics at the University of Science and Technology of China in 2011. In 2016 after his PhD graduation he achieved Rowland Fellowship and began his independent research career at Harvard as a principle investigator. He was selected as the Early Career Advisory Board of Nano Letters in 2016. He was selected as highly cited research by Clarivate in 2018. He was named as Forbes 30 under 30 in 2019, and awarded as Azrieli Global Scholar by Canadian Institute for Advanced Research (CIFAR). His research group has been focused on developing novel nanomaterials for energy and environmental applications including energy storage, chemical/fuel generation, water treatment, and so on.
