The reactions of three metal nanoparticle (MNP) systems Ru/dppb, RuPt/dppb, Pt/dppb (dppb=1,4‐bis(diphenylphosphino)butane) with gaseous D 2 at room temperature and different gas pressures have been studied using 1 H gas phase NMR, GC‐MS and solid state 13 C and 31 P MAS NMR. The main product is gaseous HD arising from the reaction of D 2 with surface hydrogen sites created during the synthesis of the nanoparticles. In a side reaction, some of the dppb ligands are decomposed producing surface phosphorus species and gaseous partially deuterated butane and cyclohexane. These findings are fundamental for detailed studies of the reaction kinetics of these particles towards H 2 or D 2 gas.
