Abstract A foam structured catalyst of ZnFe2O4-α-Fe2O3/SiC was prepared by a slurry-coating method with citric acid-nitrates as binder. Its phase composition, morphology and pore structure were characterized by XRD, SEM and BET. The influence of the concentration of citric acid-nitrates and the deposited amount of slurry on the morphology, pore structure and catalytic performance in the oxidative dehydrogenation of 1-butene of the prepared catalyst were investigated. The result show that the concentration of citric acid-nitrates hardly changed the phase composition; the as-prepared structured catalyst has a compact and neat coating with a wide range distribution of pore size; the concentration of citric acid-nitrates of the slurry or the most probable pore size of the as-prepared catalyst has a little influence on the peformance of the structured catalyst. The BET surface area and the catalytic performance of the structured catalyst gradually increased with the incresing the deposited amount of slurry. In case of gas firing hourly space velocity of bntene of 300 h-1, the conversion rate of 1-butene and selectivity of butadiene reache ca. 86% and 91%, respectively for the prepared structured catalyst with a deposited amount of 0.2 g/mL slurry, which are much higher than that for particulate catalysts, indicating superior oxidative dehydrogenation performance.
