Two-dimensional transition metal carbides as supports for tuning the chemistry of catalytic nanoparticles.

ABSTRACT: Supported nanoparticles are broadly employed in industrial catalytic processes, where the active sites can be tuned by metal-support interactions (MSIs). Although it is well accepted that supports can modify the chemistry of metal nanoparticles, systematic utilization of MSIs for achieving desired catalytic performance is still challenging. The developments of supports with appropriate chemical properties and identification of the resulting active sites are the main barriers. Here, we develop two-dimensional transition metal carbides (MXenes) supported platinum as efficient catalysts for light alkane dehydrogenations. Ordered Pt₃Ti and surface Pt₃Nb intermetallic compound nanoparticles are formed via reactive metal-support interactions on Pt/Ti₃C₂
