The water-gas shift reaction (WGSR) is a very important reaction in industrial processes in which CO and water in the vapor phase react to produce carbon dioxide and hydrogen. Copper based catalysts are considered to be the standard for methanol synthesis. Also currently, CuO/ZnO/Al2O3 (CZA) is used as the standard low temperature shift catalyst, but catalysts based on copper supported on SiO2, MgO, and Cr2O3 also have been applied. The currently used industrial CZA catalysts for WGSR are usually operated at 493�553 K. The reaction at lower temperature leads to the low reaction activity, while higher temperature results in the sintering of the catalysts. Recently, it has been demonstrated that supported gold catalysts are promising low temperature WGSR. Au/CeZrO4 catalysts are prepared by deposition-precipitation methods which have higher activity for the water-gas shift reaction and by using a model reaction gas mixture with Au supported on CeO2, TiO2 or ZrO2. The main objective of this paper is to investigate and compare the activity of Au/CeZrO4 and CZA catalyst for low temperature WGSR.
