Description

Electrochemical Hydrodesulfurization Catalyzed by Single Atoms Supported on Tungsten Disulfide Doo Young Kim, Ph.D. Department of Chemistry, University of Kentucky, Lexington, KY 40506 The high content of toxic sulfur element in fossil fuels poses a significant threat to the environment and public health. Traditional chemical processes to remove or reduce sulfur from fossil fuels have significant disadvantages, including (i) a high demand of expensive H2 and (ii) harsh reaction condition. These requirements make deep desulfurization process very costly. This proposal aims to explore a novel electrochemical process catalyzed by atomically dispersed metal atoms on layered tungsten disulfide (WS2). If successful, this research will gain fundamental knowledge of electrochemical hydrodesulfurization (HDS) process and will pave a way to a sulfur- removal process at high reaction rate, at mild condition, with a low loading of expensive catalysts, and without consuming expensive H2 gas. The project will be performed as follows. First, exfoliation will be established to obtain few-layered nanosheets WS2. Second, transition metal catalysts will be incorporated into exfoliated WS2. Lastly, electrochemical activity for the hydrodesulfurization will be determined for 3 model sulfur-containing compounds. For the mechanistic insight, operando micro-Raman spectroscopy will be employed.
