Synthesis of Graphene Oxide-Coated Mesoporous Silica with Cetyltrimethylammonium Bromide (CTAB) Template for Methylene Blue Adsorption

The synthesis of graphene oxide-coated mesoporous silica (MS_GO) with the template surfactant (Cetyltrimethylammonium Bromide) CTAB has been carried out. effect combining and oxide was studied by knowing bonds, functional groups crystalline structures. Functional C=O C=C were formed at wave numbers 1,722, 1,617 1,647 cm−1, respectively, as a characteristic GO compounds. XRD data showed that MS_GO more amorphous structure than graphite due to incorporation onto surface. also applied an adsorbent for methylene blue dye in water. adsorption results effective pure GO. percent adorption efficiency (R %) against 10 ppm 93.1 % while 91.5 %. addition makes dyes GO, this is supported larger total surface area BET 161.066 m2·g−1, 103.818 m2·g−1.
