▎ 摘  要

Commercial and chemically synthesized graphite oxides were subjected to reduction processes using two plant extracts. Ficus carica (agricultural byproduct) and Phragmites australis (aquatic macrophyte) extracts were used as alternative reducing agents to conventional chemicals to prepare reduced graphene oxide (rGO). The raw and prepared materials were characterized through UV-Vis spectroscopy, SEM-EDX, particle size distribution, elemental analysis, thermal analysis, Raman spectroscopy, FT-IR, and X-ray diffraction. Results showed the reduction capability of these plant extracts for the oxygen functional groups on the surface of graphite oxides. UV-Vis spectroscopy results are similar to that observed when chemical reducing agents are used. The X-ray diffraction peaks for the chemically synthesized and commercial graphite oxides were detected at 2 theta =10.8 degrees and 11 degrees, respectively. Subsequent to the reduction process, the peaks of rGO were observed at 24.50 degrees and 43 degrees, indicating the successful reduction of graphite oxide. The synthesized rGO samples comprised 5-7 layers.
