Pure γ-Fe2O3 was prepared by two steps. L(+)-Tartaric acid and Fe(NO3)3·9H2O were sequentially dissolved into water, then the stick liquid was dried and calcined in air. Promoter Pd and K were added to Fe2O3 by impregnation. The influence of Pd or K on Fe2O3 was different in view of the reducibility of Fe2O3, H2 and CO2 adsorption. But synergistic effects were observed from the catalyst co-promoted by Pd and K (Catalyst PKF). The improving effect of Pd on Fe2O3 reduction was further stimulated by K, and the CO2 quantity desorbed from catalyst PKF at the temperature lower than 300 °C was increased. The synergistic effects resulted in PKF having the highest C5+ selectivity for CO2 hydrogenation at 235 °C among the studied catalysts.
