Study of Perovskite Catalysts for Carbon Dioxide Conversion of Methane
摘要
This article reviews recent studies of the action of various perovskite catalytic systems for the carbon dioxide reforming of methane (CDRM). Procedures for the improvement of such perovskite catalysts are discussed. The properties of nickel, iron, cobalt, and lanthanide perovskite catalysts were found to depend on the method of synthesis and the presence of promoters such as ZrO2, CeO2, K2O, and MgO. Nanostructured perovskite catalysts with an active phase of metal nanoparticles have high activity and are stable at high temperatures. Perovskites are highly efficient CDRM catalysts. Their use as catalytic system precursor enhances the catalytic activity. Perovskites have shown high activity even under extreme high-temperature conditions, which makes them promising catalysts for CDRM. Various perovskite-based catalysts demonstrate high catalytic activity and stability even after prolonged use without coke formation.
