Enhancing the Fischer–Tropsch Synthesis Activity of Co-based Catalysts by Adding ZrO x to the SiO2 Support and Chelating Ligands to the Co-precursor

Co/ZrOx/SiO2 catalysts with enhanced dispersion of Co0 and turnover frequency were successfully prepared combining two different promotion effects, i.e., modifications of SiO2 surface with ZrOx by liquid phase deposition and influencing coordination structure of Co species using chelating agents or...

Description
Summary:Co/ZrOx/SiO2 catalysts with enhanced dispersion of Co0 and turnover frequency were successfully prepared combining two different promotion effects, i.e., modifications of SiO2 surface with ZrOx by liquid phase deposition and influencing coordination structure of Co species using chelating agents or glycols. The catalysts exhibited ~6.3-fold higher CO conversion than Co/SiO2 and those promoted by organic additives or ZrOx alone, indicating activity enhancement was induced by cooperation of these two promoters.Graphical Abstract
