One-step synthesis of bulk Mo and Ni–Mo carbides for methanation

Abstract

β-Mo2C and Ni/β-Mo2C catalysts were prepared by a single-step thermal decomposition method using hexamethylentetramine (HMT) as a reducing agent and carbon source.

New Opportunity for Carbon‐Supported Ni‐based Electrocatalysts: Gas‐Phase CO2 Methanation

“…For Mo, a major difference between our NiMo/C material and those described in the literature was the local chemical environment, with apparent segregation of Mo and no evidence of alloying in NiMo/C , as discussed earlier. In a contrasting literature example, Huo et al [52] . prepared β‐Mo 2 C and Ni/β‐Mo 2 C catalysts and investigated them in methanation of carbon monoxide.…”

Interstitial nitrides revisited – A simple synthesis of M Mo3N (M = Fe, Co, Ni)

“…There are recent examples of papers that report the catalytic activity of Ni3Mo3N obtained by ammoniation of NiMoO4. [33,[42][43][44][45][46][47] It is notable that in contrast to other η-carbide nitrides, no structural refinement exists for the putative compound Ni3Mo3N. Some authors are adamant that there is not nickel in their samples.…”

The Effect of the Ruthenium Crystallite Size on the Activity of Ru/Carbon Systems in CO Methanation

“…Due to the poor reserves of natural gas in some regions of the world, conversion of syngas from coal or biomass to synthetic natural gas (SNG) via the methanation reaction is also attracting great attention [8][9][10][11]. That is the reason why many groups are still working to obtain highly active and selective catalysts for that reaction.Supported Ni-based catalysts have been applied commercially on methanation due to their high activity, selectivity to CH 4 and low costs [1,8,11]. However, hydrogenation of CO x to methane can be catalyzed by several metals [12][13][14].…”
