SSCI-VIDE+ING:+SLI:CAQ:LGU:ATU:YSC:DFAInternational audienceThe selective oxidation of CO over C3H6 is achieved in yolk-shell Pt@Silicalite-1 catalysts in which Pt nanopartides are encapsulated in hollow silicalite-1 single crystals. The thin shell operates as a permselective membrane which limits Pt surface poisoning by C3H6. From adsorption measurements, we condude that the catalytic selectivity arises from the fastest diffusion of CO over C3H6 through the silicalite-1 membrane
