Abstract
CuFeOx/$Al_2O_3$ 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/$Al_2O_3$ and $2CuO{\cdot}Cr_2O_3$. Developed CuFeAlOx catalysts exhibited higher sulfuric acid decomposition ability than $2CuO{\cdot}Cr_2O_3$ and longer endurance trends than Pt/$Al_2O_3$ maintaining comparable performance, respectively.
