“…For the LCC-600 and LCC-850 ( Figure 4 e,f), these carbons possess rigid flakes. For carbon from coconut shell, the LCS-850 in Figure 4 h shows flatter surfaces with many voids compared with LCS-600 in Figure 4 g Therefore, morphologies of carbon depend on the material precursors and carbonization temperature, which is in agreement with the literature [ 7 ]. It is important to note that the morphologies of carbon synthesized by carbonization of lignin (lignin-derived carbon) are very different from the morphologies of porous carbon produced directly from biomass of mangosteen peel [ 29 ], corncob [ 30 ] and coconut shell [ 31 ].…”

“…These are controlled by e.g., plant age, location and management activities of a plantation. For a synthetic polymer we can adjust the pore structure and purity of materials during synthesis of the polymer [ 7 ]. Depending on the preparation method of the polymer, a hierarchical pore architecture and a monomodal pore structure (a narrow pore size distribution) can be obtained [ 8 ].…”

Porous carbon has been widely used for many applications e.g., adsorbents, catalysts, catalyst supports, energy storage and gas storage due to its outstanding properties. In this paper, characteristics of porous carbon prepared by carbonization of lignin from various biomasses are presented. Various biomasses, i.e., mangosteen peel, corncob and coconut shell, were processed using ethanol as an organosolv solvent. The obtained lignin was characterized using a Fourier transform infrared (FTIR) spectrophotometer and a viscosimeter to investigate the success of extraction and lignin properties. The results showed that high temperature is favorable for the extraction of lignin using the organosolv process. The FTIR spectra show the success of lignin extraction using the organosolv process because of its similarity to the standard lignin spectra. The carbonization process of lignin was performed at 600 and 850 °C to produce carbon from lignin, as well as to investigate the effect of temperature. A higher pyrolysis temperature will produce a porous carbon with a high specific surface area, but it will lower the yield of the produced carbon. At 850 °C temperature, the highest surface area up to 974 m2/g was achieved.

“…Porous carbon was employed as host material for the metal oxide. Porous carbon is chosen due to its excellent characteristics of high specific surface area (Ariyanto et al, 2017b;Prasetyo et al, 2017Prasetyo et al, , 2013. Cobalt oxide was impregnated within the carbon pore network to utilize the ability of this metal oxide to selectively adsorb ethylene from the atmosphere (Prasetyo, 2000…”

Ethylene is naturally generated by climacteric fruits and can promote the ripening process faster. For effective long-distance transport and subsequent storage, removing ethylene from the storage environment has been of interest to suppress its undesirable effect. In this study, ethylene removal by an adsorptive method using cobalt-loaded nanoporous carbon is studied. Cobalt oxide-loaded carbon was prepared by incipient wetness method followed by calcination process at 200 °C under inert flow. Ethylene adsorption test was performed at 20, 30, and 40 °C using a static volumetric test. The results showed that cobalt oxide/carbon system has significant ethylene adsorption capacity up to 3.5 times higher compared to blank carbon. A higher temperature adsorption is more favorable for this chemisorption process. Ethylene uptake increases from 100 to 150 mL g-1adsorbent STP by increasing cobalt oxide loading on carbon from 10 to 30 wt.% Co. The highest uptake capacity of 6 mmol ethylene per gram adsorbent was obtained using 30 wt.% cobalt oxide. Therefore, ethylene adsorption by cobalt-loaded nanoporous carbon may represent a potential method in ethylene removal and it could serve as a basis for development of ethylene scavenging material.

“…The method has the advantages of a simple design and ease of operation. Among adsorbents, porous carbon has been regarded as the most promising materials, taking advantages of its excellent physical and chemical stability and high specific surface area (500-2,000 m 2 g −1 ) [8][9][10]. Studies showed porous carbon could work to remove metronidazole from aqueous systems [11][12][13].…”

This study examined change in pore structure and microstructure of nanoporous carbon after surface oxidation and how it affects the adsorption performance of metronidazole antibiotics. The surface oxidation was performed by hydrogen peroxide at 60 °C. The properties of porous carbon were investigated by N2-sorption analysis (pore structure), scanning electron microscopy (surface morphology), the Boehm titration method (quantification of surface functional group), and Fourier transform infrared spectroscopy (type of surface functional group). The results showed that the oxidation of porous carbon by hydrogen peroxide has a minor defect in the carbon pore structure. Only a slight decrease in specific surface area (8%) from its original value (973 m2g−1) was seen but more mesoporosity was introduced. The oxidation of porous carbon with hydrogen peroxide modified the amount of oxide groups i.e., phenol, carboxylic acid and lactone. Moreover, in the application the oxidized carbon exhibited a higher the metronidazole uptake capacity of up to three-times manifold with respect to the pristine carbon.
