Abstract

Our zirconium phosphate (ZrP)-promoted Ru/Co/ZrP/SiO<subscript>2</subscript> catalyst reveals a high catalytic activity and stability during Fischer-Tropsch synthesis. Surface modification with ZrP on SiO<subscript>2</subscript> support with an appropriate amount of phosphorous component prevents cobalt particle aggregation and enhances its stability. These positive effects of ZrP are mainly induced by the spatial confinement of cobalt particles in a thermally stable ZrP matrix, and the catalytic performance was greatly improved when the P/(Zr+P) molar ratio was 0.134 on the CoZrP(0.5) catalyst.
