Effect of Cobalt Precursors on the Dispersion of Cobalt on MCM-41

摘要: Co/MCM-41 catalysts were prepared using the incipient wetness impregnation technique with aqueous solutions of different cobalt compounds such as nitrate, chloride, acetate, and acetylacetonate. MCM-41 is known to have a restricted pore structure; however, organic precursors acetate acetylacetonate resulted in very small oxide particles that could not be detected by XRD even for loading high 8 wt%. These enough fit into pores MCM-41. However, they found chemisorb CO only relatively amounts low activities hydrogenation—probably due formation silicates. The use chloride large particles/clusters and/or residual Cl--blocking active sites, and, consequently, surface area was measurable. nitrate number dispersed throughout some larger located on external Cobalt appeared best precursor preparing high-activity MCM-41-supported Fischer–Tropsch synthesis catalysts.
