Physical Adsorption at the Gas-Solid Interface

Effect of catalyst preparation conditions on the performance of eggshell cobalt/SiO2 catalysts for Fischer–Tropsch synthesis

“…Stober [9], Meyer and Heckerman [10], and Bering and Serpinski [11] indicate that a silica surface mainly consists of siloxane network in the bulk while hydroxyl groups are attached on to the "Si" surface atoms. However these groups are not similar to each other in adsorption or reaction behavior.…”
