Abstract

The hydrodesulfurization reaction of thiophene has been investigated over graphene-like few-layer MoS2 as well as over Co- and Ni-nanoparticle-covered few-layer MoS2. Conversion of thiophene to n-butane over few-layer MoS2 is superior to that over bulk MoS2; the percent conversion is approximately 64 % at 450 °C. However, over few-layer MoS2 covered with Co or Ni nanoparticles the conversion increases to approximately 98 % at around 375 °C as a result of the smaller nanoparticles being more effective.
