Porous single crystal (PSC) materials have a large specific surface area, higher structural stability, and more active sites by combining porosity and structural coherence, which provide a clear advantage in the field of catalysis. Platinum-based catalysts are precious metal catalysts commonly used in the dehydrogenation of low-carbon alkanes, with excellent dehydrogenation activity and good catalytic activity for the anaerobic dehydrogenation of ethane. By lattice reconstruction strategy we grow PSC MgO from the parent MgF₂ single crystal and load Pt nanoparticles on its surface for growing PSC Pt/MgO. Oxygen vacancies are introduced by constructing active sites on a clear surface structure, which improve catalytic activity and durability. The PSC Pt/MgO catalyst for the direct dehydrogenation of ethane achieves an ethane conversion rate of approximately 28% and ethylene selectivity of over 97%, with good stability over 100 h. The present work offers significant value for the growth and application of porous single crystal oxides loaded with metal nanoparticles.
