Relationship between the copper surface area and the activity of CuO/ZnO/Al2O3 water-gas shift catalysts Original Research Article

The catalytic activities and copper metal surface areas of CuO/ZnO/Al2O3 water-gas shift catalysts have been determined. There is no single function which can describe the relationship between the copper metal area and the activity of every catalyst. However, discrete copper area-activity relationships are evident within groups of catalysts whose precursor species were formed under identical preparation conditions. Within these groups simple, linear, area-activity relationships are discovered.
