A multilayer vanadium carbide MXene (m-V 2 C) was used as a robust oxy-carbide support to prepare a series of Ni/m-V 2 O 3 -V 2 C catalysts with various Ni amounts by an impregnation method and used for dry reforming of methane (DRM). The results show that the Ni addition increases the catalyst alkalinity, and the interaction between the Ni metal and m-V 2 C increases with increasing Ni amount. Ni/m-V 2 O 3 -V 2 C with a Ni amount of 13 wt% showed optimal CH 4 and CO 2 conversions of 94 % and 89 %, respectively. In addition, 13Ni/m-V 2 O 3 -V 2 C exhibits excellent catalytic stability and anti-coking ability in a 90-hour stability test, which is attributed to the strong metalsupport interaction. In situ DRIFTS analysis showed that methane activated on the Ni particles generates CH x and H, while CO 2 interacts with m-V 2 O 3 -V 2 C to form carbonates on Ni/ m-V 2 O 3 -V 2 C; carbonate species come into contact with methane pyrolysis products and quickly form formate species, which are further decomposed into CO.
