摘要：

The chemisorption of diborane on silica gel strongly influences the porosity of the structure. A method, based on a cylindrical pore model, is proposed to probe the pore-narrowing as well as the pore-blocking of a mesoporous silica gel. It was observed that pore-narrowing increases linearly with the averge pore diameter, while pore-blocking decreases with an increasing pore diameter. The proposed method proved to be suitable for semiquantitative application.
