Synthesis and Characterization of Fe2O3 Doped Graphene by Co-precipitation Method

One way to enhance the physical properties of Fe2O3 is by graphene doping. In this research, the synthesis of Fe2O3 doped graphene involved various treatments, i.e. non-sintering, sintering at 600°C for 1 hour, and sintering at 700°C for 1 hour. The phase identification results suggested that single-phase Fe2O3 doped graphene could be obtained without sintering and the smallest diameter generated was 70.19 nm. The morphology characterization showed that all the three materials had a particle size of less than 100 nm, but the non-sintered material was the most favorable one due to its homogeneous nanospheres. The FTIR spectrum shows the presence of O-H, C-H, CO2, C-O, C-N, and CH2 groups. The non-sintered Fe2O3 doped graphene had the highest peak at 3307.92 cm⁻¹, and the O-H group appeared. The Fe2O3 doped graphene sintered at 600°C for 1 hour had the highest peak at 3410.33 cm⁻¹, and the O-H group appeared. The Fe2O3 doped graphene sintered at 700°C for 1 hour had the highest peak at 3410.33 cm⁻¹, and the O-H group appeared. The C=C peak was around 1500–1600 cm⁻¹, while the C-O-C peak was around 1230–1320 cm⁻¹. Taken together, the synthesis of Fe2O3 doped graphene using a simple co-precipitation method could produce a single-phase material without sintering.
