Abstract

Cu-Ce_0.8Zr_0.2O₂ and Cu-Ce_0.2Zr_0.8O₂ catalysts have been applied for water gas shift reaction to understand the effect of cubic/tetragonal structure of CeO₂-ZrO₂ support. Cubic Cu-Ce_0.8Zr_0.2O₂ catalyst shows higher activity (17.4% at 320°C) than tetragonal Cu-Ce_0.2Zr_0.8O₂ catalyst at the high gas hourly space velocity of 72,152h^-1 due to the enhanced oxygen mobility and high Cu dispersion (7.8%). In addition, cubic Cu-Ce_0.8Zr_0.2O₂ catalyst exhibits a stable activity at 320°C for 25h resulting from a strong resistance against sintering.
