Cavity engineering has been great attraction in material sciences due to its demand for various applications such as supercapacitor, lithium battery, adsorbents, and membranes. Therefore tremendous efforts have focused the development of newly porous materials with high specific surface area. Nowadays, graphene oxide (GO) has been regarded as a starting material for porous materials due to its easy processability and tunable properties. Namely, the oxygen-functional groups offer the opportunities for chemical functionalization and the carbon provides the chances for activation to prepare porous structures. Here, we have proposed the facile method for preparing porous structures based on GO to introduce silica sol-gel process with chemical activation to achieve improved material porosity as well as high specific surface area. The preparing materials were studied on its chemical structures, morphologies, and surface area of GO/silica hybrid with porous structures. |
