| Abstract: | Porous graphene (PG) has potential applications in numerous fields because of the existence of nanopores in the plane. In this study, porous graphene decorated silica microspheres (Sil-PG) were successfully fabricated by assembling PG onto the silica particles surface in deep eutectic solvents (DESs). Experimental results demonstrate that this new stationary phase can facilitate the separation of six sulfonamides compounds in hydrophilic chromatographic conditions. The successful synthesis of the SilPG stationary phase provides a basis for the application of porous graphene-modified materials as the stationary phase for liquid chromatography, and offers the possibility to broaden the application of PG in the field of chromatography. |
