Metal carbide catalysts are essential to many widely used chemical processes. Fischer‐Tropsch synthesis, methane dehydroaromatization and biomass conversion catalysts are typically prepared in situ from a metal oxide precursor with a carbon‐containing gas. The reduction process of the metal oxide affects the final catalyst, as does the carburization gas mixture and metal promoters. By looking at materials that are carburized in situ, new insights can be gained about catalyst activation, fuel processing, and deactivation stages. The main focuses of this Review are iron carbide, molybdenum carbide and nickel carbide; analyzing catalyst synthesis methods, reduction steps, in situ carburization and improvements to the native processes. By combining years of research on these catalysts, trends and similarities are observed that can be used to improve current catalytic studies.

A SiO 2-supported MoO 2 nanoparticle catalyst was synthesized by a sol-gel method and tested as catalytic material for the partial oxidation of n-dodecane. MoO 2 nanoparticles supported on SiO 2 are < 10 nm in size and show a resistance to sintering at 850 o C, which is a typical reforming temperature for ndodecane. The formation of MoO -Si bonds at the interface between MoO 2 nanoparticles and SiO 2 support appear to be directly related to the enhanced stability to sintering displayed by the nanoparticles. As a result of this particle size stabilization, SiO 2 supported MoO 2 nanoparticles show an improved reforming activity in terms of syngas generation compared to micron-size commercial MoO 2. Thus, commercial MoO 2 exhibits a good initial activity at space velocities up to 15 h-1 , but showing only gas-phase reactions at larger values. Conversely, MoO 2 nanoparticles supported on SiO 2 show a high initial reforming activity (e.g., 69% H 2 yield, 82% CO yield and 100% carbon conversion) even at space velocities up to 30 h-1. Supported MoO 2 nanoparticles also show good stability for the partial oxidation of n-dodecane at 850 o C without any sign of deactivation during the first 24 h on-stream. 10 mol% MoO 2-SiO 2 CO Yield H 2 Yield Conversion MoO 2 10 mol% MoO 2-SiO 2 at WHSV 30 h-1
