Abstract
The water gas shift (WGS) reaction has been investigated widely in fuel cell technologies due to the potential for high fuel efficiency and lower emissions during the production of pure hydrogen. Industrially, the WGS reaction occurs in one of the following two ways: (a) high-temperature in the range of 310-450 ℃ with Fe-Cr catalyst, (b) lowtemperature in the range of 210-250 ℃ with Cu-ZnO-Al2O3. In this study, a mesoporous catalyst was prepared, with a large surface area and uniformity in both pore size and distribution, by using a one-pot synthesis method. The prepared CuO-CeO2-Al2O3 brought high CO conversion (82%), and was suitable for WGS reaction at low temperature (250 ℃).
