The　catalytic　properties　of　ZnO-modified　copper　ferrite　in　water-gas　shift　(WGS)　reaction　were　evaluated　between　250　and　400　.　The　Zn2.5-Cu/Fe　(modified　by　2.5%　ZnO)　showed　high　catalytic　activity.　The　catalyst　was　characterized　with　XRD,　SEM,　H2-TPR　and　CO2-TPD　techniques　and　N2　sorption　experiment.　It　was　shown　that　introduction　of　appropriate　amounts　of　ZnO　transformed　the　CuFe2O4　from　the　tetrahedral　crystalline　phase　to　the　cubic,　enhanced　the　CuFe2O4　reducibility,　and　increased　the　amount　of　weak　and　medium　basic　sites.　As　a　consequence,　the　interaction　between　copper　and　iron　species　was　improved　and　the　catalytic　activity　was　increased.　©,　2014,　Science　Press.　All　right　reserved.
