Abstract:

Because of their extraordinary features, graphene oxide and other 2D carbon  nanomaterials have sparked a surge in scientific interest recent years. In this work, four distinct graphene oxide synthesis methods were employed and compared: Brodie, Staudenmaier, Hummers and Modified Hummer's method. The three different effect on graphite was focused on each method. In the first case, no pre-treatment of graphite was carried out. In the second case, the graphite was ultrasonicated, and in the third case, graphite sample was preheated at 200 °C for 3 h. The atomic ratio of carbon to oxygen (C/O) with EDS analysis, G (1350 cm⁻¹) peak intensity ratio of D (1590 cm⁻¹) peak intensity (ID/IG), and G peak intensity ratio of 2D (2680 cm⁻¹) peak intensity (I2D/IG), from RAMAN analysis, surface area (SA) measurement from BET analysis, the particle size distribution (PS), polydispersity index (PDI) values, and zeta potential from ZETA-SIZER (ZP) analysis. From the selected quality criteria, the performance of graphene oxide synthesized by no pre-treatment of graphite with the Modified Hummers method turned out to be better than other methods. Recovery rates according to no pre-treatment of graphite with the Modified Hummers method were obtained as 73.78%, 19.40%, 86.43%, 171.65%, 76.84%, 5.26%, and 28.73%, respectively, for C/O, D/G, 2D/G, SA, PS, PDI, and ZP.

Keywords: Particle size analyses; BET analyses; Graphene oxide synthesis; Hummers method; Brodie and Staudenmaier method
