Key Points

This research aims to elucidate the catalytic mechanisms in CO2-assisted propane dehydrogenation.
Investigated the effects of ZnO on oxygen vacancies and CO2 adsorption.
Revealed the coupled tandem oxidative mechanism through experimental data.
Employed molecular dynamics and microkinetic modeling for analysis.
ZnO significantly enhances oxygen vacancies and CO2 adsorption.
The CTO mechanism shows effective coupling of propane with CO2-derived oxygenates.
Microkinetic modeling confirms increased propylene production through C-C coupling.

Implication

Uncovers propylene amplification in propane dehydrogenation, indicating new catalytic pathways.

Abstract

• 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.
