CuFeAlOx 촉매상에서의 황산분해 반응

Abstract

CuFeOx/Al2O3 catalysts are developed for the use in sulfuric acid decomposition which is a subcycle in thermochemical iodine-sulfur cycle to split water into hydrogen and oxygen. Both Cu and Fe components are co-precipitated with Al component to enhance distribution of active components. Developed catalysts are improved in the capability of sulfuric acid decomposition and endurance under highly acidic environment compared to commercial catalysts such as Pt/Al2O3 and 2CuOCr2O3. Developed CuFeAlOx catalysts exhibited higher sulfuric acid decomposition ability than 2CuOCr2O3 and longer endurance trends than Pt/Al2O3 maintaining comparable performance, respectively.
