Carbon Oxidation - an overview | ScienceDirect Topics

Direct oxidation carbon coulometry (DOCC) is a direct quantitative cleanliness verifiion method that is cost-effective, rapid, easy to perform, surface-texture independent, and adaptable to production environments [81–84]. The technique employs in-situ direct oxidation of surface carbon to carbon dioxide (CO 2), followed by automatic CO 2

Novel graphite-molybdenum carbide nanocomposites (G-Mo 2 C) are synthesized by a typical solid state reaction with melamine and MoO 3 as precursors under inert atmosphere. The characterization results indie that G-Mo 2 C composites are composed of high crystallization and purity of Mo 2 C and few layers of graphite carbon. Mo 2 C nanoparticles with sizes ranging from 5 to 50 nm are
