Assessment of pore structure parameters for polymer-templated mesoporous molecular sieves by means of nitrogen and argon adsorption
Pore size, wall thickness, and microporosity of polymer-templated mesoporous silica (PTMS) can be controlled by using different nonionic triblock copolymers as soft templates. The evolution of the pore structure of PTMS was studied by using nitrogen and argon adsorption at 77 K in addition to powder X-ray diffraction and transmission electron microscopy.
