Synthesis and Characterization of Reduced Graphene Oxide from Fiber of Borassus Flabelifer by Activation Method

Abstract

Reduced Graphene Oxide (RGO) has been successfully synthesized by calcination process at 4000C for 4 hours followed by activation with NaOH 1 M. Carbonization is the last process with variations in heating at 6500C, 7500C, 8500C, and 9500C for 1 hour (heating rate 100C / minute). DSC-TGA data shows that there is advanced decomposition at high temperatures, this is confirmed by SEM data which shows the amount of porosity which is getting higher with a size that decreases with temperature. XRD data shows phase differences at low temperatures with a trend of higher levels of crystallinity at high temperatures. Raman spectroscopy data showed an ID / IG ratio of 2.607 and 1.007 on Borassus Flabelifer L with carbonization at 6500C and 9500C respectively. The ID / IG value which is getting closer to 1 indicates that the carbon available in Borassus Flabelifer L has undergone phase changes such as Graphene with a little Oxide commonly called RGO

Isotherm Adsorption Kinetics Study of Methylene Blue on Reduced Graphene Oxide from <i>Borassus flabelifer </i>L Fiber

“…The heating causes decomposition of the impurity compound which makes it leave the material and leaves a hole in the form of a pore. Based on the DSC-TGA graph by Fandi, et al [13] on fibers Borassus Flabelifer L, decomposition occurs especially in liginine from 200°C to 600°C. In this study, based on SEM results, it was shown that the pores formed were < 10 μm in size.…”

“…In this study, a material in the form of fiber of Borassus flabelifer L was used which had not previously been used as a dye adsorbent for textile waste. In a previous study, the fiber of Borassus flabelifer L was treated to form Reduced Graphene Oxide (RGO) phase [13] in order to enhance the adsorption efficiency which was applied as a supercapacitor electrode [14]. In this study, Fiber of Borassus Flabelifer L was treated with different treatments to form RGO phase as well, so that it is expected to be able to absorb textile color waste better.…”
