| this feature is not evident for the Co/SBA-15, but this is due to the fact that the desorption occurs at the critical pressure of liquid nitrogen. the observed decrease in surface area is higher than what would be obtained by only taking the mass increase upon cobalt loading into account, suggesting the presence of cobalt species inside the porous network in all cases. |
