“…Thus, the adsorption mechanism referred to as electrostatic interactions, hydrogen bonds, π-π stacking interactions, pore filling, hydrophobic interactions, ion exchange, and also other interactions (n-π interactions, etc.) and complexation reactions can take place [30,184,187,194,197,203,205,220,[226][227][228]. The micropores and mesopores of the porous network of activated carbon contribute to the adsorption of pollutants by pore-filling mechanisms according to their total volume and the size of the pollutant molecules, and this is influenced by the affinity of the adsorbent with respect to the pollutant [229].…”

The π-π stacking interactions are suggested for the sorption of aromatic compounds on the surface of activated carbon containing aromatic rings, suggesting the presence of graphene in the carbon [205].

Porous materials constitute an attractive research field due to their high specific surfaces; high chemical stabilities; abundant pores; special electrical, optical, thermal, and mechanical properties; and their often higher reactivities. These materials are currently generating a great deal of enthusiasm, and they have been used in large and diverse applications, such as those relating to sensors and biosensors, catalysis and biocatalysis, separation and purification techniques, acoustic and electrical insulation, transport gas or charged species, drug delivery, and electrochemistry. Porous carbons are an important class of porous materials that have grown rapidly in recent years. They have the advantages of a tunable pore structure, good physical and chemical stability, a variable specific surface, and the possibility of easy functionalization. This gives them new properties and allows them to improve their performance for a given application. This review paper intends to understand how porous carbons involve the removal of pollutants from water, e.g., heavy metal ions, dyes, and organic or inorganic molecules. First, a general overview description of the different precursors and the manufacturing methods of porous carbons is illustrated. The second part is devoted to reporting some applications such using porous carbon materials as an adsorbent. It appears that the use of porous materials at different scales for these applications is very promising for wastewater treatment industries.

Organic carbon is also a potential 5–7 due to the sources are abundant feedstock from agriculture product. Recently, organic carbon materials have attracted considerable attention due to the oxygen bonding at the surface for their functionalization to enhance the adsorption capacity 8–10 and act as the organic linker in contact with metal 9–12 .…”

Electronic properties of composite Fe and activated carbon (AC) were determined by using X‐ray photoelectron (XPS) and reflection electron energy loss (REELS), structural properties by X‐ray diffraction (XRD), and photo‐catalytic performance by ultra violet visible (UV‐Vis) spectroscopy. The intensity of low loss spectrum shows surface state at 5.42 eV is decreased with increasing the amount of AC indicated the Fe successfully oxidizes to form iron oxide. The bandgap was increased from 2.2 eV for 10% AC to 4.3 eV for 25% AC indicated the absorption wavelength shifted from the visible region to ultra‐violet region. The magnetic properties and porosity were increased with increasing the amount of AC in composites and show successfully used, as a magnetic trap of the charge (electron and hole) for producing radical atoms. The magnetic pore transformed from the disordered to ordered nature in the periodic structure was used to accelerate the degradation from 70.15% for 10% AC to 80% for 25% AC for 60 min. This study shows magnetic trap of composite Fe‐AC materials useful for enhanced photocatalytic performance.

Adsorption equilibrium and kinetics studies of effect of ortho-substituted benzoic acid in aqueous phase using granular activated carbon were investigated. The granular activated carbon (GAC) obtained from bituminous type coal having a surface area of 998 m 2 /g and loosely bounded and open pores morphology. The adorbates selected for this study was benzoic acid and its ortho-derivatives namely; salicylic acid, phthalic acid and o-toluic acid. The solubility of adsorbate in solvent affected the adsorption behaviour more pronouncly. The order of adsorption for adsorbates was found to be as: benzoic acid > salicylic acid > o-toluic acid > phthalic acid.
