Fabrication of graphene and N-doped graphene aerogels and evaluating their electrical, mechanical, and adsorption capability properties: Fullerenes, Nanotubes and Carbon Nanostructures: Vol 0, No 0

Summary

On this examine, Nitrogen-doped (N-doped) graphene as a superb multifunctional materials was ready and its properties was in contrast with undoped graphene aerogels. The aerogels had been ready utilizing drying technique at ambient stress. Ammonia was used as a nitrogen supply to make N-doped graphene aerogel. The density of the ready graphene aerogel was measured 15.37 mg/cm³ and that of N-doped graphene aerogel was 12.81 mg/cm³. Morphology, porosity and chemical composition of samples had been characterised by scanning electron microscopy, X-ray diffraction, nitrogen uptake measurement, X-ray power diffraction spectroscopy, and infrared spectroscopy. Mechanical and electrical properties of each aerogels had been measured and in contrast. Additionally, adsorption capability of crude oil, petrol, cooking oil and gasoline by graphene and N-doped graphene aerogels had been measured and located that adsorption capability of N-doped aerogels is larger. The best uptake adsorption capability of graphene and N-doped graphene aerogels for crude oil was 33 gg⁻¹ and 42 gg⁻¹, respectively.
