Unveiling the coupled tandem oxidative mechanism in CO2-assisted propane dehydrogenation over a ZnO-promoted VOX/SAPO-34 catalyst
• ZnO enriches oxygen vacancies, enhances reducibility, and strengthens CO 2 adsorption. • CTO mechanism revealed: propane couples with CO₂-derived oxygenates. • MD and microkinetic modeling confirm propylene amplification via C–C coupling.
