BACKGROUND: Mesoporous double-layer carbon microspheres (DCSs) were synthesized using hollow tin(IV) oxide (SnO 2 ) microspheres as hard template and sucrose as carbon precursor via the hydrothermal method. Sulfonic acid groups (-SO 3 H) were introduced onto the surfaces of DCS by sulfuric acid heating and sulfanilic acid diazonium coupling, respectively, to form two solid acids (DCS-SS and DCS-DS, respectively). RESULTS: The transmission electron microscopy images showed that the carbon microspheres possessed a hollow double-layerstructure with diameters of about 200 to 300 nm and shell thickness of about 30 to 50 nm. Furthermore, the sulfonate treatments caused no changes in the morphology of carbon microspheres. The nitrogen (N 2 )-Brunauer-Emmett-Teller (BET) results indicate that DCS, DCS-SS, and DCS-DS featured mesopores with an average pore size of 4.5 to 4.8 nm and BET surface areas of 75 m 2 /g, 57 m 2 /g, and 53 m 2 /g, respectively. The X-ray photoelectron spectroscopy and Fourier-transform infrared results confirmed that the DCS-SS and DCS-DS contained a -SO 3 H group and their surface acid densities are 4.5 and 4.1 mmol/g, respectively.CONCLUSION: DCS-SS and DCS-DS were used to catalyze the transesterification of waste frying oil, and the highest yields of fatty acid methyl esters, that is, 85% and 80%, respectively, could be obtained. CONCLUSIONThe sulfonated mesoporous DCS (DCS-SS and DCS-DS) were successfully prepared. DCS-SS and DCS-DS possessed average pore sizes of 4.1 to 4.5 nm, BET surface area of 53 to 57 m 2 /g, J Chem Technol Biotechnol 2019; 94: [3538][3539][3540][3541][3542][3543][3544][3545][3546][3547]

“…A previous study reported the efficiency of the hydrolysis reaction of cellulose in nitric acid solution and converted cellulose to glucose using salicylic acid as a catalyst [7]. The hydrolysis rate of cellulose increased when activated carbon having both carboxyl and phenolic hydroxyl groups was taken as a catalyst [8]. These studies show that such hydroxyl groups can be used as catalysts for the hydrolysis reaction of cellulose.…”

Activated carbon was prepared using bagasse and carbon fiber (RCF) recycled from carbon fiber reinforced polymer (CFRP). The RCF surface has a sufficient amount of functional groups and can be used as a catalyst for the hydrolysis of bagasse cellulose. An RCF‐bagasse composite was fabricated by ultrasonic irradiation. During cellulose hydrolysis, carbon from the bagasse was activated with sulfuric acid, which impregnated the cellulose pores. When bagasse was subjected to high temperatures, the impregnated pores decomposed, resulting in micropores. The addition of RCF increased the specific surface area of activated carbon by up to 20 % when heat treatment was performed at a temperature higher than the carbonization temperature of bagasse.

“…The interaction renders enhanced mass transfer rates between the catalysts and cellulosic materials and thereby high hydrolysis efficiencies. This finding inspires studies on a variety of carbon-based catalysts prepared from different raw materials, such as mesoporous carbon (CMK-3) (Pang et al, 2010), mesoporous silicon oxide/carbon composite (Van de Vyver et al, 2010), magnetic oxide/sulfonated carbon shell composite , graphene oxide (GO) (Kitano et al, 2009;Verma et al, 2013;Zhao et al, 2014;Mission et al, 2017;Zhang et al, 2017), and lignin Zhu et al, 2016;Gan et al, 2017;Wang et al, 2020;Zhu et al, 2020). In these studies, GO-based catalysts demonstrate excellent performance for cellulose hydrolysis.…”

Glucose produced by catalytic hydrolysis of cellulose is an important platform molecule for producing a variety of potential biobased fuels and chemicals. Catalysts such as mineral acids and enzymes have been intensively studied for cellulose hydrolysis. However, mineral acids show serious limitations concerning equipment corrosion, wastewater treatment and recyclability while enzymes have the issues such as high cost and thermal stability. Alternatively, solid acid catalysts are receiving increasing attention due to their high potential to overcome the limitations caused by conventional mineral acid catalysts but the slow mass transfer between the solid acid catalysts and cellulose as well as the absence of ideal binding sites on the surface of the solid acid catalysts are the key barriers to efficient cellulose hydrolysis. To bridge the gap, bio-inspired or bio-mimetic solid acid catalysts bearing both catalytic and binding sites are considered futuristic materials that possess added advantages over conventional solid catalysts, given their better substrate adsorption, high-temperature stability and easy recyclability. In this review, cellulase-mimetic solid acid catalysts featuring intrinsic structural characteristics such as binding and catalytic domains of cellulase are reviewed. The mechanism of cellulase-catalyzed cellulose hydrolysis, design of cellulase-mimetic catalysts, and the issues related to these cellulase-mimetic catalysts are critically discussed. Some potential research directions for designing more efficient catalysts for cellulose hydrolysis are proposed. We expect that this review can provide insights into the design and preparation of efficient bioinspired cellulase-mimetic catalysts for cellulose hydrolysis.
