Advancements and prospects of perovskite materials for catalytic combustion of light alkanes

Light alkanes (LA), as strong greenhouse gases and atmospheric pollutants, pose a significant challenge for efficient removal at low temperatures in environmental catalysis. Catalytic combustion offers a green and effective solution to reduce the emission of LA, with catalyst selection and modification as its core. Perovskite materials have emerged as promising alternatives to precious metals due to their tunable crystal structures, low cost, and excellent thermal stability. This review summarizes recent advances (2010-2025) in perovskite catalysts for the catalytic combustion of light alkanes (CLA). It discusses strategies to enhance the low-temperature activity, poisoning resistance and durability of perovskite catalysts. Through precise control of perovskite physicochemical properties, the deep oxidation of LA can be significantly promoted. Finally, the paper analyzes current challenges in developing efficient perovskite catalysts and envisions future directions. These insights aim to provide a scientific foundation for designing next-generation catalytic materials for air pollution control.
