We have demonstrated Ni doped Co₃O₄ can enhance the propane oxidation performance and verified the Mars-van Krevelen reaction mechanism by operando DRIFTS and isotope oxygen exchange. The catalyst stability characterized by Raman, XPS and XRD shows a balance between promoted catalytic activity and decreased thermal stability is needed for practical application.
