“…Among various solid acid catalysts that have been exploited for the production of acetals, carbon‐based materials have drawn some research attentions owing to their low costs from the viewpoint of industrilization [12–15] . For examples, Gonçalves and co‐workers [16] reported the use of acidic carbon‐based catalysts derived from biodiesel wastes for effective acetalization of glycerol.…”

A series of transition metal (M)-promoted carbonsilicon (CÀ MÀ Si; M = Mn, Fe, Co, Ni, Cu, Zn, Zr) solid acid catalysts with designated molar ratio of M/Si = 1 : 8 were fabricated and exploited for acetalization of benzaldehyde (BzH) with ethylene glycol (EG). The physical and chemical properties of these CÀ MÀ Si catalysts prepared by sol-gel method were characterized by various techniques, namely, SEM, EDS, TGA-DTG, BET, XRD, FTIR, XPS, and NH 3 -TPD. Among various examined acidic CÀ MÀ Si catalysts, the CÀ FeÀ Si catalyst exhibited the optimal catalytic activity with the benzaldehyde glycol acetal (BEGA) yield of 97.67 %, in excellent agreement with the value (97.88 %) predicted by the response surface methodology (RSM) based on a Box-Behnken design (BBD). CÀ FeÀ Si catalyst with the high catalytic activities and excellent stability and reusability may be ascribed to the suitable acidity and uniform surface distribution of active sites requisite for the acid-catalyzed acetalization reaction.

“…The −SO 3 H group catalyzed cellulose depolymerization is a widely researched topic in heterogeneous catalysis where −SO 3 H groups are generally immobilized on a solid surface such as carbon, graphene, silica, or polymeric support. − However, the use of −SO 3 H group based catalysts in the homogeneous phase is rare, and in our previous work we have studied the catalytic activities of a series of alkyl/aryl sulfonic acids in water for the hydrolysis of sigmacell cellulose to reveal the superior activity of some hydrophobic aryl sulfonic acids when compared to sulfuric acid. For instance, high molecular weight cellulose hydrolyzed in dilute aqueous solutions of p -toluenesulfonic, 2-naphthalenesulfonic, and 4-biphenylsulfonic acid mediums produced total reducing sugar (TRS) yields of 28.0, 25.4, and 30.3%, respectively, in comparison to 21.7% TRS produced in aqueous sulfuric acid under similar conditions.…”

Efficient catalytic hydrolysis of lignocellulosic biomass to sugars is a major challenge in the production of sustainable biofuels and chemical feedstocks. In this study isethionic acid was compared with H 2 SO 4 for hydrolysis of polysaccharides in corn stover, switch grass, and poplar. The catalytic activities of acids were compared by analysis of total reducing sugar (TRS) and glucose yields in a sequence of experiments in water at 90−190 °C using 0.050 mol of H + /L isethionic acid and H 2 SO 4 . In comparison to using H 2 SO 4 , the use of isethionic acid catalyst lowered the maximum TRS percent yield temperatures by 25, 24, and 21% for corn stover, switch grass, and poplar. A similar effect was observed for glucose percent yields as well. This temperature reduction is due to lowering of the activation energy in the polysaccharide depolymerization reaction and most likely due to hydrogen-bonding-type dipolar interactions between the isethionic acid −OH group and −OH groups in biomass polysaccharides.

“…In addition to the conventional applications of activated carbon, such as adsorbent materials [1][2][3], removal of heavy metals [4,5], electrochemical capacitors [6,7], energy storage [8,9] and catalyst carriers [10,11], ultrafine activated carbon can be applied in the pharmaceutical field as a negative carrier for the slow release of drugs [12,13], or removing facial impurities, detoxifying, and relieving inflammation [14,15]. Xu [16] used ultrafine coal-based activated carbon (UCAC) obtained by grinding granular coal-based activated carbon with filter water, and achieved a total organic carbon removal rate of 82%, which was a 50% increase over coal-based activated carbon (CAC).…”

Coal-based activated carbons (CACs) have excellent valuable applications, and have been industrially produced. However, ultra-fine coal-based activated carbons (UCACs) and their removal of methylene blue (MB) have rarely been reported in the present literature. Two kinds of UCACs were obtained in this paper and the adsorption test of MB was carried out. The adsorption performance of MB on UCAC was simulated by Grand Canonical Monte Carlo (GC-MC) method. The experimental results were validated by molecular simulation, and the adsorption mechanism was investigated. The adsorption amount of MB, the d50, and specific surface area values of the UCACnew (obtained by the new method) and UCACcm (obtained by the conventional chemical method) were 746.95 mg/g, 12.54 μm, 1225.36 m2/g and 652.77 mg/g, 12.10 μm, 713.76 m2/g, respectively. The results of the molecular simulation calculations were consistent with the pattern of magnitude of the experimental results. The peak of the adsorption concentration occurred near 6 Å on the pore surface. The interaction energy of MB molecules with carboxyl groups was much larger than with hydroxyl groups. Van der Waals forces dominated the adsorption process, with a contribution of >60% in both cases.
