“…It was also found that the pore volume of the organoclays decreased with increasing length of the surfactant alkyl chain. The intercalation of the large DTAB and CTAB cations may have resulted in blocking of the interlamellar space, which inhibited the passage of nitrogen molecules [36][37][38][39]. Moreover, the surfactant cations not only entered into the clay interlayer space but were also adsorbed on the exterior surface, mainly as a monolayer [18][19][20][21][22].…”

“…In this case, the loaded surfactant occupied the pores available between clay particles with a "house of cards" structure. This resulted in a decrease in the specific surface area and pore volume [39][40][41]. From these results, it was assumed that the surface area and pore volume are not important factors in terms of controlling the affinity between organoclays and organic pollutants [42].…”

“…Up to now, most researches have been only focused on the reutilization of crab shells or chitin from crab shells as bioadsorbents to remove heavy metals. [6][7][8][9] Activated carbons (ACs) with high surface area, large pore volume and hierarchical microporous/mesoporous structure are widely used in various elds, including adsorption, 10 gas separation/storage, 11,12 catalysis supporter 13 and electric double-layer capacitors (EDLCs). 14 However, the commercial ACs derived from relatively expensive and non-renewable starting materials such as coals, are high cost and unjustied to the pollution control applications.…”

Crab shell, an abundant food waste and high volume organic resource, has been used to synthesize oxygen-enriched activated carbon. The thermal stability, surface area, morphology and surface chemical composition were characterized by thermogravimetric analysis, nitrogen adsorption, scanning electron microscopy, energy dispersive X-ray spectroscopy, Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy. The obtained activated carbon had a high surface area of 3442 m 2 g À1 , large pore volume of 2.327 cm 3 g À1 and rich surface oxygen species of 18.50 at%. The cyclic voltammogram, galvanostatic charge-discharge and electrochemical impedance spectroscopy tests were performed to investigate the electrochemical properties of the resultant carbon electrodes. The specific capacitance was 280.6 F g À1 at a current density of 0.2 A g À1 and still remained as high as 233.4 F g À1 even at a high current density of 10 A g À1 , indicating the great potential of crab shellactivated carbons in the development of electrode materials for high-performance supercapacitors.

“…Activated carbon/clay hybrid AC/clay composites were prepared in monolithic forms with different wall thicknesses and channel widths, and as solid and tubular extrudates [152][153][154]. The adsorption capacity of AC/clay was studied in terms of vapor pressure of the gas to adsorb and the pore size distribution of the resulting composites.…”

This paper provides a concise review of recent advances in activated carbon (AC) and its corresponding modified material. Topics covered in this work include the synthesis and characterization of AC as the feedstock materials, as well as the properties and applications of the subsequent hybrid material for different industries. Numerous research studies have since reported remarkable physical, chemical, thermal, conductivity, porosity, and mechanical (stiffness and strength) properties of AC in different types of multiple material matrices, including polymers, metals, and ceramics. The incorporation of AC particles into material matrices may result in the formation of an entire new class of advanced materials, due to the resulting strong interfacial bonds of the hybrid components. Although this requirement is no different from those that offer conventional hybrid materials, the scale of the reinforcement and filled phase of the AC has changed from micrometers to nanometers. This create opportunities to increase the potential applications of AC hybrid materials of the development of fundamentally unique new materials for in chemical conversion, environmental, and fuel storage applications.
