Synthesis of Sustainable Acid Biochar Catalysts Derived from Waste Biomass for Esterification of Glycerol

“…Another bands appeared at 1616, and 1403 cm −1 suggesting the attendance of an aromatic C=C ring stretching and bending vibrations of −CH 2 [26] . In addition, the bands could be observed at 1032, 873, and 692 cm −1 , which corresponding t to −C−N stretching present in aliphatic carbon, in‐plane and out‐of‐plan −NH 2 vibrations of carbon [29] …”

“…[26] In addition, the bands could be observed at 1032, 873, and 692 cm À 1 , which corresponding t to À CÀ N stretching present in aliphatic carbon, in-plane and out-of-plan À NH 2 vibrations of carbon. [29] Raman spectra of biochar catalysts are displayed in Figure 6. Two bands were detected at 1310 cm À 1 and 1597 cm À 1 in the Raman spectra.…”

Sustainable porous carbons from tannic acid based KOH activated as high-performance CO2 capture sorbents

“…[6][7][8][9] Various factors such as the distribution of pore sizes of solid sorbents regulate their capacity for CO 2 adsorption. Micropores, in particular those with #1 nm diameter (classied as narrow micropores), are involved in the adsorption of CO 2 at low pressure (#1 bar), [10][11][12][13] whereas at high pressure (e.g., 30 bar) small mesopores ranging in size from 2-4 nm have a key role in CO 2 uptake. [14][15][16] Therefore, porous materials with controlled pore size properties, such as metal-organic frameworks (MOFs), 17,18 microporous polymers, 19,20 and zeolites, 21,22 are of signicant use for CO 2 capture and are a subject of extensive research.…”

Preparation and characterization of activated carbon modified by potassium for carbon dioxide/methane adsorption and separation

“…There are myrid materials used as adsorbents, including activated carbons, graphene and its relative materials, zeolites, metal organic frameworks [6–11]. Activated carbons have been utilized generally due to their developed pore structure, extensive raw materials, and price moderate [12]. However, their adsorption capacity still needs to be further improved, which can be achieved by modifying their chemical and physical properties [12–14].…”

“…Activated carbons have been utilized generally due to their developed pore structure, extensive raw materials, and price moderate [12]. However, their adsorption capacity still needs to be further improved, which can be achieved by modifying their chemical and physical properties [12–14]. For example, basic maters have been adopted to enhance the adsorption capacity and separation efficiency since the introduction of basic functional groups into the adsorbent surface is favorable to adsorption of acidic gas such as carbon dioxide [15, 16].…”
