However, a limited understanding of the nature of active sites and structure–activity relationships continues to pose challenges for the rational design of high-performance catalysts in this sustainable process. This study elucidates the interplay between Cr and Co metal oxides in CrCo binary oxide catalysts by varying the Cr/Co weight ratio. Cr<sub>4</sub>Co<sub>1</sub> catalyst, which contains a high Cr concentration, demonstrated the highest activity, achieving 31 ± 1 % propane conversion and 66 ± 1 % propene selectivity.
