Abstract
Described herein are catalysts relating to liquid synthesis, methods of their preparation, and methods of their use. In an embodiment according to the present disclosure, a method of producing a catalyst for liquid synthesis comprises: providing a silica oxide support; pretreating the silica oxide support to remove air and moisture; impregnating the pretreated silica oxide support with cobalt from a cobalt source using a cobalt impregnation method; and calcinating the impregnated silica oxide support in an oven with a temperature ramping profile, wherein the calcinating comprises feeding air into the oven.
