By manipulating the preparation conditions, in this case solvent, precipitating temperature, and pH, a Cu surface area of 45.5 +/- 1.7 m(2)/g was prepared, which was much greater than the surface area of 11.4-31.7 m(2)/g obtained by the conventional co-precipitation method and seemed to be the largest Cu surface area ever reported in the literature. The preparation of catalysts with a high Cu surface area was attributed to the formation of aurichalcite, a complex containing Cu and Zn. The catalysts prepared by the modified co-precipitation method were used for a water-gas shift reaction, exhibiting higher catalytic activity compared to those prepared by the conventional co-precipitation method.
