Abstract 

A series of zirconia-supported LaCo0.7Cu0.3O3 catalysts with different LaCo0.7Cu0.3O3 content were prepared by impregnating ZrO2 with lanthanum, cobalt and copper nitrate and citrate acid, and the prepared samples were characterized by XRD, TEM and H2-TPR techniques. The synthesis of alcohol from syngas was performed in a stainless-steel continuous fixed-bed flow micro-reactor. After reduction, the catalyst precursor favored to form nanoparticles of Co-Cu alloy highly dispersed on ZrO2 and modified with La2O3. The metal nanoparticles of Cu-Co alloy together with ZrO2 modified with La2O3 contributed to the excellent selectivity of alcohols and higher alcohols.
