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.
