Researchers create nanoparticles to solve environmental problems |
Stony Brook researchers, in collaboration with scientists from Brookhaven National Lab (BNL) and the US Air Force Laboratory, have developed a new generation of nanoparticles to solve environmental problems. In their recent work, featured on the cover of Journal of Physical Chemistry C, Alexander Orlovteacher at Department of Materials Science and Chemical Engineering in the College of Engineering and Applied Scienceshis students and collaborators have created ultra-small gold nanoparticles capable of removing carbon monoxide from the air.
The novelty of this work comes from a very special method of making such nanoparticles, where gold vapor infuses super cold helium droplets and creates a very uniform jet of catalysts. The unique equipment used to produce liquid helium is based at the US Air Force laboratory, with further research conducted at BNL’s Center for Functional Nanomaterials, under the direction of Mingzhao Liu and Xiao Tong.
Haotian Yang, PhD student in Orlov Laboratory and first author of the published paper “Enhancing CO Oxidation Activity via Tuning a Charge Transfer Between Gold Nanoparticles and Supports”, offered a novel explanation for the activity of gold toward CO oxidation. carbon. This work may have important implications for designing better nanomaterials to solve pressing environmental problems.
