“…Each sample generated a diffraction peak in the 2⊔ range of 0.9-1.1°, indicating a two-dimensional hexagonal structure in the 100 plane. 29 In addition, the OMC, OOMC and OOMC-SO 3 H each produced two weak peaks in the range of 2⊔ = 1.5-2.0°, which correspond to twodimensional hexagonal structures in the 110 and 200 planes. 30 The OOMC-SO 3 H retained an ordered structure, which was consistent with the TEM results.…”

BACKGROUND: A novel double acid site solid catalyst (Al-OCS-0.1) having an ordered mesoporous structure was synthesized by grafting sulfonic acid groups on an oxidized ordered mesoporous carbon (OOMC) support and loading 10% Al 2 (SO 4 ) 3 .RESULT: Assessments using Field emission scanning electron microscopy, Transmission electron microscopy and X-ray diffraction showed that the OMC structure remained unchanged after the chemical modification and Al 2 (SO 4 ) 3 loading. The Brunauer-Emmett-Teller surface area and average pore size of Al-OCS-0.1 decreased to 181 m 2 g −1 and 7.1 nm after loading Al 2 (SO 4 ) 3 , respectively. Ammonia temperature-programmed desorption (NH 3 -TPD) and Pyridine adsorption infrared spectroscopy (Py-IR) demonstrated that Al-OCS-0.1 had abundant Brønsted and Lewis acid sites. The ammonia desorption of Al-OCS-0.1 increased from 2.0 to 7.2 mmol g −1 after loading Al 2 (SO 4 ) 3 .CONCLUSION: The Al-OCS-0.1 was used to catalyze the synthesis of ethyl levulinate from cellulose in ethanol and gave an extremely high yield of 50.8 mol% after 5 h at 200 °C.

“…Where CCl 4 and ethylenediamine (EDA) represent precursors whereas silica act as a hard template [53] (see Figure 4). While Wei Liu, Hong Yuan, and Yihu Ke Prepared ordered mesoporous carbon-based on soybean oil by using the hard template method where a hard template is represented by ordered mesoporous SiO 2 molecular sieves (SBA-15) [55].…”

Nanoporous carbon-based sorbents are used to generate a three-dimensional real-space model of the nanoporous structure using the concept of Gaussian random fields. This pore model is used to derive important pore size characteristics, which are cross-validated against the corresponding values from gas sorption analysis. After filling the model pore structure with an aqueous electrolyte and rearranging the ions via a Monte Carlo simulation for different applied adsorption potentials. In comparison to nanopores formed from solid-state membranes (e.g., silicon oxide, aluminum oxide, polymer membranes, glass, hafnium oxide, gold, etc.) and very recently 2D materials (e.g., boron nitride, molybdenum disulfide, etc.), those nanopores produced from carbon materials (e.g., graphene, carbon nanotubes (CNTs), diamond, etc.), especially those from graphene appear to be perfect for adsorption process. The thickness of carbon structures nanopores can be as thin as 0.35 nm, resembling the height of the base spacing. Moreover, the sizes of carbon structures nanopores can be precisely fabricated and tuned to around 1.0 nm, the similar size of many heavy metals and organic pollutants molecules. Furthermore, carbon materials are chemically stable and feature-rich surface chemistry. Therefore, various carbon nanopore sequencing techniques have been developed. Finally, in this chapter the adsorption of phenolic compounds on nanoporous carbon specifically the active carbon are overviewed and how to affect the heterogeneity of activated carbon surface, PH of the solution on the efficiency of adsorption.
