Already commonly used industrially in the hydrodesulfurization process, MoS2 is a promising catalyst that can exist as a stable monolayer film, much like graphene. This poster describes a method for growing MoS2 monolayers on a copper substrate at a relatively low temperature and under mild sulfurization conditions throug the use of thiophenol. Additionally, this procedure yields other molybdenum sulfide structures, including Mo2S3 films and Mo6S6 nanowires. To analyze the catalytic activity of these structures, we titrate using anthraquinone and formic acid as test molecules, thus determining the relative affinities for adsorbate interactions.
