Abstract Joule-heating reactors have the higher energy efficiency and product selectivity compared with based on radiative heating. Current are constructed electrically-conductive metals or carbon materials, therefore suffer from stability issue due to presence of corrosive oxidizing gases during high-temperature reactions. In this study, chemically-stable (La 0.80 Sr 0.20 ) 0.95 FeO 3 (LSF)/Gd...
