Facile and economical preparation method of nanoporous graphene/silica nanohybrid and evaluation of its Pickering emulsion properties for Chemical Enhanced oil Recovery (C-EOR)

摘要

In this research, we have proposed a very simple and economical preparation method for nanoporous graphene/silica nanohybrid (sol-gel method) that the related Pickering emulsion will be suitable for Chemical Enhanced Oil Recovery (C-EOR). This preparation method is preferred to the similar previous researches. For evaluation of the mentioned Pickering emulsion properties, we have prepared other carbon structures (MWCNT and graphite)/SiO2 nanohybrids with different weight percent. The as-prepared nanomaterials were characterized with X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM) and Thermal Gravimetric Analysis (TGA).
