Thermo-gravimetric analysis reveals that all activated carbon samples were thermal stable up to ~ 850 °C. FTIR spectrum shows appearances of minor functional groups in the activated carbons.doi:10.1007/s40034-020-00176-zGeeta KumariBhavin Soni...
Fig. 2. (a) FTIR spectrum of OP-AC. (b) Raman spectra of OP-AC. (c) Adsorption/desorption isotherm of OP-AC. The intensity of Raman spectral lines are characterized by using the Raman spectroscopy which is shown in the Fig. 2b. The Raman spectra was carried out in the range of 50...
The production of activated carbon from eucalyptus wood chips by steam activation in a 2000 kg batch intermittent rotary kiln with continuous carbonization–steam activation process conducted at 500 °C to 700 °C was studied. The activated carbon products were characterized by FTIR, SEM–EDS, Raman...
Fig. 4. FTIR spectrum of PPy@V2O5@carbon hybrid nanocomposite. 3.4. BET isotherms The type V isotherm and H3 hysteresis loop are displayed in the BET adsorption isotherm of the PPy@V2O5@carbon hybrid nanocomposite (Fig. S2) [29]. The measurements show that the average pore diameter is 12.18...
The FTIR analysis showed that the reaction was successful, and methylene blue was present on the adsorbent surface. The methylene blue adsorption test indicated that 388 mg/g of the dye was adsorbed (97% dye removal), and the final concentration reached 6 mg/L after 8 h. The point of ...
The amount of material lost during the physical activation step followed the order Control > Zinc chloride > Phosphoric acid-activated carbon. However, the % Hardness surprisingly also followed the same order. We would have expected that increase in material hardness would translate into ...
The material is a black amorphous carbon material made by activated sludge that came from water treatment, which is made by blending, carbonization, activation, and so on. It has the characteristic of a dense pore, complex pore structure, and large specific surface area; so, it has higher ...
The TEM images of (a) Fe3O4 nanoparticles, (b) activated carbon, (c) Fe3O4/AC-NH2 composite and (d) EDS spectra of Fe3O4/AC-NH2. The functional groups on Fe3O4, Fe3O4/AC and amine-functionalized Fe3O4/AC nanocomposite were investigated by FTIR spectroscopy and the spectra are...
OCDs, including carbon nanotubes, carbon nanofibers, and carbon dots, mainly employ advanced syntheses, for example, nanotechnology. Currently, ACs and OCDs are mainly characterized using advanced techniques like scanning electron microscopy (SEM), Fourier transform infrared (FTIR) spectroscopy, ...
For samples with CB, the high-resolution XPS spectrum of C 1s can be deconvoluted into four major peaks (Fig. S2). The binding energies at 284.9, 287.8, 288.3, and 286.5 eV are assigned to sp2-hybridized graphite-like carbon (sp2 CC), CO, CO and COC, respectively. As seen in Fig....
