Visible active enhanced adsorptive performance of the green synthesized Sulphur and Nitrogen codoped reduced graphene Oxide towards Degradation of reactive blue 4

The present study proposed a green way to synthesize Sulphur (S) and Nitrogen (N) codoped reduced graphene oxide (SN-rGO) employing a simple, efficient, and environmentally effective method. The graphene oxide (GO) sheets were integrated with S and N heteroatoms and were synthesized in an ecological manner employing bone meal extract (BME) as a green reducing agent. FTIR, FESEM, EDX, XPS and UV-Visible spectroscopy were used to evaluate the functional chemical bonding, surface morphology, chemical structure, and elemental compositions of the SN-rGO nanomaterial. The outcomes of the experiment have notably proved that SN-rGO possesses uncountable remarkable catalytic properties. In brief, UV-visible and Fourier transform infrared (FTIR) spectroscopies demonstrated the efficient synthesis of SN-rGO. The FESEM and HRTEM results indicated the crumbled, folded, and interconnected geometries of the networks that verified the surface modification and integration in the rGO sheets. The elemental composition of the SN-rGO nanomaterial was validated simultaneously by the EDAX and XPS analysis. The S and N doping may give additional carriers for reactive sites, hence enhancing the absorption of Reactive Blue 4 (RB4) was researched and addressed.
