Characterization of Cobalt Dispersed on Various Micro- and Nanoscale Silica and Zirconia Supports

Cobalt dispersion on various micro- and nanoscale SiO2 and ZrO2 was investigated. It revealed that Co/SiO2 (M) exhibited higher activity than Co/SiO2 (N) due to strong support interaction. However, Co/ZrO2 behaved oppositely. In addition, Co dispersed on the nanoscale SiO2 and ZrO2 gave the similar activity for CO hydrogenation because of more uniform species.
