The metallic components have been denoted as CxZyAz, with the subscripts x, y and z being the atomic ratios corresponding to Cu/Zn/Al. The ratio values studied are 1.0:1.0:0, 2.0:1.0:0 and 4.5:4.5:1.0. The addition of ZnO sig-nificantly enhances Cu metal dispersion and avoids its sintering.Furthermore, the addition of a small amount of Al2O3 increases the BET surface area and pore volume, thereby increasing the specific metal surface area (Cu dispersion is enhanced)
