Inorganic Materials Aims and scope

Abstract—

This paper presents results of an experimental study concerned with vacuumless arc discharge synthesis of ultrafine molybdenum carbide-based materials. We have found discharge circuit parameters that ensure an essentially complete conversion of starting molybdenum. The synthesis product contained micron-sized crystals and graphene-like carbon structures, with molybdenum carbide nanoparticles embedded in them. We present preliminary results on the catalytic activity of the synthesized materials, without modification with precious metals.
