Abstract

Abstract The direct dehydrogenation of alkanes to olefins under mild conditions is challenging due to the inert nature of alkyl C─H bonds. Herein, an efficient photocatalytic system is developed for propane direct dehydrogenation (PDH) to propylene, consisting of ≈1.30 nm sized PtO2 clusters immobilized on a layered double hydroxide ‐derived ZnO/Al2O3 support (LD‐Ptn). Under UV excitation (365 nm), photogenerated holes in ZnO migrate to Pt sites at PtO2/ZnO interfaces, thereby activating and dissociating C─H bonds in propane. A propylene production rate of almost 1 mmol g−1 h−1 and a nearly 100% selectivity are achieved for the compositionally optimized LD‐Ptn photocatalyst. Control experiments and density functional theory calculations further verify that the excellent photocatalytic PDH performance of LD‐Ptn stems from synergism between ZnO semiconductor and the loaded Pt species. This work identifies a promising new route for direct production of olefins from alkanes.
