Nanosized, yet ordered: Active and selective Pd2Ga intermetallic compounds supported on carbon nanotubes have been synthesized and applied to alkyne hydrogenation. Intermetallic compounds on the nanoscale are necessary to achieve high mass activity, whereas ordered structures within intermetallic compounds form high barriers for subsurface chemistry and prevent large active ensembles on Pd surface.
