Molybdenum carbide Chemical Properties,Usage,Production
Description
Molybdenum carbide belongs to the transition metal carbide, which is a family of interstitial compounds with metallic properties formed by carbon entering the crystal lattice of the transition metal.
Chemical Properties
Molybdenum carbide is a gray hexagonal crystal. It has the characteristics of high melting point and hardness, good thermal and mechanical stability and good corrosion resistance. The melting point is 2692°C. Insoluble in water and lye, slightly soluble in nitric acid, sulfuric acid and hydrofluoric acid.
Uses
Molybdenum carbide has a high initial catalytic activity in the benzene hydrogenation reaction. Although the catalyst gradually deactivates as the reaction progresses, its steady-state conversion frequency (TOF) is still comparable to that of noble metals Pt or Ru.
In the transition metal carbides series, molybdenum carbide has proven as an effective catalyst for the hydrogen evolution reaction (HER). This article will introduce the performance of molybdenum carbide as catalyst.
