Abstract

Transition metal carbides and nitrides demonstrate very interesting electrocatalytic properties, close to those of noble metals. Indeed,platinum being a scarce and expensive element, carbides and nitrides could be an interesting alternative to make this technology economically viable. Recently, different authors reported promising (electro)catalytic properties of molybdenum carbides and nitrides. Herein we report the synthesis of Mo nitrides and carbides from original routes using transition metal cluster-based precursors or laser pyrolysis. The resulting nitrides and carbides were characterized by several complementary techniques (XRD, BET, SEM, etc.). These innovative modes of synthesis afford nanostructured compounds and the evaluation of Mo5N6 for the WGS reaction is reported.
