چکیده مقاله:
The increasing worldwide energy demand and environment concerns lead to extensive research to develop sustainable and environment-friendly alternative energies to replace exhaustible fossil fuels. Hydrogen, as a renewable and clean energy resource, has been proposed as a potential candidate for future fuel owing to its high energy density and environmental friendliness [1]. Pt- based materials are the effective catalysts in hydrogen evolution reaction, but they are expensive and difficult to recycle, so that their application is impeded in the development of economical hydrogen energy [2]. Recently, transition metal disulfides (TMDs) have received tremendous attention as hydrogen evolution reaction (HER) catalysts due to their favorable chemical and catalytic properties [3].In this research, the MoS2 and BCN nanostructures were synthesized through sulfurization of MoO3 powder and milling methods. Carbon-based nanocomposite containing MoS2 and BCN nanostructures in appropriate ratio were prepared under optimum condition. The synthesized nanostructures were characterized by FTIR, XRD and FESEM-EDX to determine functional groups, crystalline structures, morphology and elemental analysis. The performance of synthesized nanocomposite was investigated as a nanocatalyst for hydrogen production. The effective parameters on process efficiency were investigated and optimized. The obtained results showed that this nanocatalyst improves the process of hydrogen production. Also this catalyst exhibits high stability, suggesting that this nanocomposite is a good candidate for the hydrogen evolution reactions.
