One-step synthesis of hierarchically porous silicas with multilamellar vesicular core and ordered mesostructured shell

Hierarchically porous silicas with multilamellar vesicular core and ordered mesostructured shell have been successfully synthesized using a simple one-step method through a soft dualtemplating approach. The vesicular core has irregular cavity size generally larger than 100 nm, while the pore size of the shell is 9.8 nm, which may have potential applications in loading and controlled release of large molecules.
