Zn Doping Effect on the Performance of Fe-Based Catalysts for the Hydrogenation of CO to Light Hydrocarbons.

In this work, we studied the role of zinc in the composition of supported iron-containing catalysts for the hydrogenation of CO. Various variants of incipient wetness impregnation of the support were tested to obtain catalyst samples. The best results are shown for samples synthesized by co-impregnation of the support with a common solution of iron and zinc precursors at the same molar ratio of iron and zinc.
