The low-temperature water-gas shift reaction (WGSR) is already used in several industrial chemical processes. However, interest in this reaction has increased significantly in the last few years because of the advances in fuel cell technology and the need to develop compact reformers for the production of pure hydrogen streams (free from CO). In the present work, the WGSR was carried out on copper-based supported catalysts, one of them already used in the industry and the other one prepared using the sol-gel method with the same composition as the industrial catalyst. The synthesized sol-gel catalyst presented excellent catalytic performance, with a very stable CO conversion of around 60%. The high activity and stability of the sol-gel catalyst were mainly attributed to its large metal surface area and high copper dispersion.
