Abstract

This paper describes a non-aqueous, solvent-free, environmentally friendly, one-pot facile reaction to synthesize inorganic materials inclusion with carbon (MoS₂ or MoSe₂/C) at low temperatures. Nanoflakes of MoS₂ and MoSe₂ inclusion with carbon are prepared by a thermal (750 °C) reaction between Mo(CO)₆ and S or Se at their autogenic pressure in a closed reactor under inert atmosphere. Elemental sulfur or selenium powders are chosen in order to avoid the use of highly toxic H ₂S and H₂Se gases. Without further processing of the as-prepared MoS₂/C or MoSe₂/C products, their compositional, morphological and structural characterization are carried out. The possibility of hydrogen storage in as-synthesized MoS₂/C or MoSe₂/C products is examined. A probable reaction mechanism for the formation of MoS₂ or MoSe₂ nanoflakes inclusion with C is discussed.
