Ba0.5Sr0.5FeO3, SrMn0.5Fe0.5O3, and BaMn0.5Fe0.5O3 perovskite catalysts were synthesized via the hydrothermal method. The developing perovskite catalysts with dual bed, redox and acid/base sites, for direct oxidation reactions is one of the recent/important research ideas. Therefore, this study deals with the impact of substituting A and/ or B sites on the catalytic oxidative reactivity of mixed oxides perovskite catalysts. Then, their reactivity was tested in a single reactor oxidative coupling of methanol/ethanol mixture for sustainable acrolein production. The Ba0.5Sr0.5FeO3 perovskite sample has the highest catalytic performance at low temperatures (300○C) with 78% acrolein selectivity, followed by SrMn0.5Fe0.5O3 (65%), then BaMn0.5Fe0.5O3 (58%). The enhanced catalytic reactivity of Ba0.5Sr0.5FeO3 is associated with its effective acidic property and the ability to form O-vacancies easily, so, the strong proclivity for C–C coupling formation.
