Direct Formation of Mesoporous Coesite Single Crystals from Periodic Mesoporous Silica at Extreme Pressure
Under an extreme pressure of 12 GPa, mesoporous coesite can be formed directly from periodic mesoporous silica without the aid of a template. The porous coesite particles obtained from SBA‐16 are single crystalline, with a pore size of about 4 nm and about 50 % porosity. The formation can be attribu...

Summary: | Under an extreme pressure of 12 GPa, mesoporous coesite can be formed directly from periodic mesoporous silica without the aid of a template. The porous coesite particles obtained from SBA‐16 are single crystalline, with a pore size of about 4 nm and about 50 % porosity. The formation can be attributed to the kinetically controlled crystallization of a nonporous elastically strained glasslike silica intermediate (see scheme). |
