Abstract
MCM‐41 and MCM‐48 were functionalized with cobalt by two methods, incipient wetness impregnation and co‐precipitation, and were characterized by XRD, N2‐sorption, and TPR. The incipient wetness impregnation method provides a high dispersion of small cobalt oxide particles, while the mesoporous structure and high surface areas are maintained. There seems to be a higher dispersion of cobalt oxide on the three‐dimensional MCM‐48 than on the one‐dimensional MCM‐41. The co‐precipitation method did not precipitate easily reducible cobalt oxide in any sizable amounts; instead, the cobalt was mainly bound as cobalt silicate.
