We report a facile " one - pot " method for the synthesis of Sn - embedded carbon - silica ( CS ) mesostructured ( nanostructured ) composites through the selective interaction of resol ( carbon precursor ) , tetraethylorthosilicate ( TEOS ) , and tributylphenyltin ( Sn precursor ) with an amphiphilic diblock copolymer , poly ( ethylene oxide - b - styrene ) , PEO - b - PS .
 Chemical: Sn; Chemical: carbon; Chemical: silica; Chemical: carbon; Chemical: tetraethylorthosilicate; Chemical: TEOS; Chemical: tributylphenyltin; Chemical: Sn; Chemical: poly ( ethylene oxide - b - styrene ); Chemical: PEO - b - PS
