“…Recently, much attention has been devoted to obtaining activated carbons from post-agricultural and post-industrial waste products, for example from walnut shells, fruit skins and stones, timber production waste [15][16][17][18][19], used car tyres or phenol-formaldehyde resins and waste sediments posing serious challenge to waste management [20][21][22][23]. The possibility of their use for production of carbon adsorbents can significantly contribute to resolution of the problems with utilisation of waste products.…”

Activated carbons have been obtained by physical activation of residue left after supercritical extraction of hops. The effect of pyrolysis temperature on the physicochemical properties of the adsorbents prepared was tested. The carbonaceous materials were characterised by low-temperature nitrogen sorption, determination of pH and the number of surface oxygen groups. The thermal properties of the chars and activated carbons were identified by thermogravimetric analysis and differential thermogravimetry. The products of thermochemical treatment of the starting hops were carbonaceous adsorbents of specific surface area ranging from 2 to 416 m 2 g-1 , showing definitely basic character of the surface and moderate thermal stability as evidenced by a considerable mass loss at about 300-400°C. The results obtained in our study have proved that residue left after supercritical extraction of hops (or similar plant materials) can be cheap, easily accessible and promising precursor for activated carbons. The results have also shown that future research should be aimed at the optimum choice of the temperature of carbonation and activation in order to significantly improve the textural parameters of the activated carbons as well as their thermal stability.

“…As indicated in Figure 2 b, three peaks at 531.9, 533.4, and 536.0 eV were attributed to C=O, C–OH, and O=C–OH [ 26 , 27 ]. The C 1s spectrum is divided into three peaks with binding energies of 286.3, 285.4, and 284.6 eV, corresponding to C–S, C=N, and C–C/C=C [ 28 ]. In the S 2p spectrum ( Figure 2 c), the peaks at 160.5 and 162.7 eV correspond to S 2p 1/2 and S 2p 3/2 , respectively, whereas the peak at 164.08 eV is attributed to C–S–C bonding [ 29 , 30 , 31 , 32 ].…”

There is great demand for high-performance, low-cost electrode materials for anodes of lithium-ion batteries (LIBs). Herein, we report the recovery of carbon materials by treating waste tire rubber via a facile one-step carbonization process. Electrochemical studies revealed that the waste tire carbon anode had a higher reversible capacity than that of commercial graphite and shows the positive effect of ZnS in the waste tire carbon. When used as the anode for LIBs, waste tire carbon shows a high specific capacity of 510.6 mAh·g−1 at 100 mA·g−1 with almost 97% capacity retention after 100 cycles. Even at a high rate of 1 A·g−1, the carbon electrode presents an excellent cyclic capability of 255.1 mAh·g−1 after 3000 cycles. This high-performance carbon material has many potential applications in LIBs and provide an alternative avenue for the recycling of waste tires.

“…Activated carbon contains the kind of surface functional groups, such as aromatic compounds, aliphatic compounds, hydroxyl group, carbonyl group, and a carboxyl group. These groups play an important role in terms of chemical adsorption and electrostatic interaction with chemicals [41]. Chemical treatment of activated carbon (KA HCl) activation has a higher adsorption ability than activated carbon with a non-chemical treatment (KA).…”

This paper focused on the studying of adsorption properties of Fe3O4-waste paper activated carbon composites for the removal of methylene blue dyes from water. The various parameters were carried out for the adsorption test of the composites, namely; contact time, adsorbent dose, initial MB concentration, pH solution, and temperature. The adsorption of isotherm, thermodynamics and kinetic was used to determine the characteristics of methylene blue adsorption onto the prepared adsorbent. The result indicates that the optimum adsorption capacity has occurred at pH = 6 in water solution. The adsorption capacity increase as the temperature increase until at 315K (45oC). The Langmuir isotherm is more appropriate to be applied as the adsorption model with the maximum adsorption capacity (qm) value of 101 and 93 mg/g for KA HCl-Fe3O4 and KA-Fe3O4 composites, respectively. The value of adsorption thermodynamic parameters was positive for ΔH, negative for ΔGo and positive for ΔSo, meaning the process adsorptions were endothermic, feasibility and spontaneity and randomness, respectively. The pseudo-second-order model was appropriate to predict the kinetic models for methylene blue adsorption onto the composites. The obtained adsorbent composites possess high adsorption efficiency and rapid magnetic separation. They were a promising for practical wastewater treatment for dyes removal from water.
