It was early recognised, that early transition metal carbides and nitrides featured catalytic activities similar to the ones of platinum group metals (PGMs). Such ceramics thus attracted a lot of attention, especially from people interested in oil refining and petrochemistry. The use of urea as either a carbon or a nitrogen source enabled the synthesis of various early transition metal nitrides and carbides nanoparticles (TiN, Mo3N2, WN, NbC, Mo2C and W2C). The ability of these particles to promote the alkylation of ketones with alcohols was tested on benzyl alcohol and acetophenone at 150°C for 20h. All the tested ceramics proved able to catalyse the formation of 1,3-diphenyl propenone. TiN featured the highest activity and was further tested for more difficult alkylations. Interestingly, group VI ceramics promoted Friedel-Crafts reactions. This ability was also studied.
