Abstract
Metal-support interaction offers electronic, geometrical and compositional effects to tune and maneuver catalytically active sites. Here we report the first example of a reactive metal support interaction (RMSI) between Pt and various MXenes, which are two-dimensional (2D) metal carbides, nitrides, or carbonitrides. The invention thus provides intermetallic Pt/MXene nanoparticle catalysts comprising platinum and MXene moieties. PtTi and PtNb intermetallic nanoparticle catalysts were prepared by RMSI of Pt nanoparticles supported on TiCand NbC MXenes. The intermetallic structures were verified by XAS, ARSTEM, and XPS. Experimental analysis showed that the extent of alloy formation is temperature dependent. Kinetics analysis revealed that in contrast to Pt/AlO, Pt supported by NbCTexhibits weaker CO adsorption and the alloy-MXene interface shows enhanced ability of HO dissociation for a water gas shift (WGS) reaction at 300° C. The catalysts also show improved selectivity and stability for alkane dehydrogenation compared to Pt.
