Seoul National University (SNU) College of Engineering announced that a research team led by Professor Jeong Woo Han of the Department of Materials Science and Engineering has developed a new nanostructured catalyst with up to 14.4 times higher greenhouse gas decomposition performance compared to conventional commercial catalysts.
Seoul National University (SNU) College of Engineering announced that a research team led by Professor Jeong Woo Han of the Department of Materials Science and Engineering has developed a new nanostructured catalyst with up to 14.4 times higher greenhouse gas decomposition performance compared to conventional commercial catalysts.
The research team synthesized a new nanostructure, termed “nanomace,” by chemically bonding ceria (CeO₂) nanocubes and nanorods. They revealed that the boundary where the two crystal structures meet serves as a key active site where catalytic reactions occur most actively.
The nanomace catalyst reduces the use of expensive precious metals typically required to enhance catalytic performance, while offering broad applicability in automobile exhaust purification, industrial emission reduction, greenhouse gas removal, and clean hydrogen production. As such, it is expected to accelerate the commercialization of eco-friendly energy and environmental technologies.
The research findings were published in the prestigious international journal Nature Communications. Notably, the study was selected for the journal’s “Editors’ Highlight: Catalysis Focus” section, which features outstanding research in the field of catalysis.
