Cu/CeO2-ZrO2catalysts　for　water-gas　shift　(WGS)　reaction　were　prepared　with　co-precipitation　method,　and　the　influence　of　ZrO2content　on　the　catalytic　structure　and　properties　was　investigated　by　the　techniques　of　N2physical　adsorption　analysis,　XRD　and　H2-TPR.　The　results　indicate　that　the　BET　surface　areas　of　the　catalysts　are　increased　in　varying　degrees　due　to　the　presence　of　ZrO2.　With　increasing　ZrO2content,　the　pore　size　distribution　is　centered　on　1.9　nm.　ZrO2can　efficiently　restrain　the　growth　of　Cu　crystal　particles.　The　appropriate　amount　of　ZrO2in　the　Cu/CeO2catalysts　can　help　the　catalyst　keep　better　copper　dispersion　in　the　WGS　reaction,　which　can　lead　to　both　higher　catalytic　activity　and　better　thermal　stability.　When　ZrO2content　is　10%　(atom　fraction),　Cu/CeO2-ZrO2catalyst　reaches　a　CO　conversion　rate　of　73.7%　at　the　reaction　temperature　of　200°C.
