摘要

•Robust NiSn subnanoclusters are successfully encapsulated within silicalite-1 zeolite.•Synergy of NiSn sites is conducive to selective C–H activation and propylene desorption.•Propylene productivity of Ni1Sn1@S-1 catalyst is restored after 3 regeneration cycles.•Dehydrogenation mechanism is revealed from in situ FTIR spectra.
