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 have been ready utilizing drying technique at ambient strain. 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 have been characterised by scanning electron microscopy, X-ray diffraction, nitrogen uptake measurement, X-ray vitality diffraction spectroscopy, and infrared spectroscopy. Mechanical and electrical properties of each aerogels have been measured and in contrast. Additionally, adsorption capability of crude oil, petrol, cooking oil and gasoline by graphene and N-doped graphene aerogels have been measured and located that adsorption capability of N-doped aerogels is increased. The best uptake adsorption capability of graphene and N-doped graphene aerogels for crude oil was 33 gg−1 and 42 gg−1, respectively.
