“…Generally, carbon is the most prominent element in all the samples indicating the polymeric nature of the PANI and GR. Theoretically, the constituents of this PANI should be carbon, hydrogen, nitrogen and chlorine, while graphene is said to be the sp 2 hybridized monolayer of carbon atoms which are arranged in a hexagonal honey-comb structure [9,22], this definition tells us that there shouldn't be any other element present in the graphene sample. However, the presence of oxygen in PANI is probably due to traces of adsorbed moisture from the atmosphere or PANI sample not properly dried after synthesis.…”

Our lives are dependent on materials and/or technology, which unfortunately come with a tremendously huge luggage of "dirt". That is its production involves the usage of chemicals, which could be hazardous (i.e. volatile organic solvents) towards both human beings and the environment [1]. A memorandum of understanding was signed by different nations to address the issue of hazards they are faced with and this gave birth to what is known as "Green Chemistry". This green chemistry has been addressed through outreach initiatives, research, implementation and education. In terms of research, Green Chemistry has been practiced in several industries such as in solvents, catalysis, polymers, renewables, analytical methods development, design of safer chemicals and the development of synthetic methods. Therefore, to ensure a cleaner future, chemists went back to the drawing board to

“…The main peaks of PANI are located at 2u = 158, 20.58 and 25.28, illustrating that the products are in highly doped emeraldine salt form [38]. PG10 shows almost the same peaks as PANI except for a small peak at 438 coming from the graphite-like structure of GN [43,44].…”

Abstract. Reduced graphene oxide (rGO) was synthesized using sonication-assisted oxidation of graphite followed by reduction with ascorbic acid as environmentally friendly reductor. The polyaniline was prepared via chemical polimerization of aniline in 0℃. The rGO and polyaniline were blend in three mass compotitions of 1:3, 1:1, and 4:1 to produced rGO/polyaniline nanocomposites. The rGO/polyaniline nanocomposites were characterized using Raman spectroscopy, Fourier transform infrared spectroscopy and LCR meter. The rGO sheets as the support materials could provide more active sites for the nucleation of polyaniline, where polyaniline acts as conducting support. The rGO/polyaniline nanocomposites was deposited on synthetic graphite substrate laminated the glass substrate and applied as the counter electrode for efficient dye sensitized solar cells (DSSC). The rGO/polyaniline nanocomposite is an efficient counter electrode because of Pt/TCO free. The usage of rGO/polyaniline nanocomposites film as counter electrode in DSSC was demonstrated. The best performance was obtained for rGO/Polyaniline ratio of 4:1. Here, the optimum short circuit current density (Jsc), the open circuit current (Voc), the fill factor (FF), and the overall conversion efficiency under AM 1.5, 100 mW cm −2 illumination are 7.853 mA/cm 2 , 0.64 Volt, 47.2% and 2.64%, respectively.
