“…4,5 In light of "green chemistry", carbonaceous catalysts are versatile and have emerged as promising solid catalysts for chemical reactions. 6,7 Cinnamomum longepaniculatum, belonging to the Lauraceae family, is rich in essential oil (main source of eucalyptol). For this reason, C. longepaniculatum has been widely cultivated and distributed in southwestern China as an economic crop, especially in the Yibin region (Sichuan province).…”

The catalytic behavior for 5-ethoxymethylfurfural (5-EMF) formation was systematically studied via facile conversion of sucrose under a sustainable ultrasonic-biphasic system using an active ZnO nanofiber-deposited-SO 3 H-carbon catalyst (Zn-S-C). Interestingly, 5-EMF with a high yield could be easily obtained and separated from ethanol/tetrahydrofuran (THF) via green synthesis-extraction procedures in the presence of NaCl. Meanwhile, an actual 5-EMF yield of 93.5 ± 0.8% was successfully achieved at 98 °C for 47 min using a THF amount (0.25 mol) and catalyst adding amount (77.8 wt %) over the combination of 2 k factorial and Box−Behnken designs. The product selectivity and yield from sucrose conversion were systematically controlled by adjusting type/amount of catalyst, co-solvents or inorganic salts, and ultrasonic system. The activation energy (38.17 kJ/mol) obtained from ultrasound-assisted conversion of sucrose into 5-EMF was lower than that from the conventional system. Strikingly, a nonsignificant decrease in the turnover rate (TOR, min −1 ) for conversion of sucrose into 5-EMF appeared when the catalyst was reused up to 100 cycles, indicating long-life cycle stability of the as-prepared catalyst.

“…In addition, the use of biomass‐derived catalysts instead of conventional transition metal‐based catalysts may also contribute to the high waste recovery while simultaneously reducing the waste disposal issues of the agricultural sector. Today, the SBC and SAC catalysts used for biodiesel production are majorly derived from agricultural residues such as coffee residue, [ 35 ] oil palm empty fruit bunch (EFB), [ 36 ] palm kernel shell (PKS), [ 2 ] bamboo, [ 37 ] glucose, [ 38 ] pine wood sawdust, [ 39 ] pine needle, [ 40 ] coconut shell, [ 6 ] cow dung, [ 41 ] sugarcane bagasse, [ 42 ] wood powder, [ 43 ] corn cobs, [ 44 ] orange peel, [ 45 ] rice husk, [ 46 ] murumuru kernel shell, [ 47 ] palm seed cake, [ 48 ] and so on. These low‐cost ubiquitous waste carbon precursors are not only nontoxic, noncorrosive, biodegradable, high availability, consist of high amount of carbon composition, but also uncomplicated to be processed as they do not require any pretreatment steps.…”

Sulfonated carbon‐based catalysts (SCC) are favorable heterogeneous acids for acid‐catalyzed reactions including esterification and transesterification for biodiesel production. They are covalently functionalized with SO3H groups via CPhSO3H or CSO3H linkages with special carbon structures. To date, the types of SCC for biodiesel production ranges from biochar (BC), activated carbon (AC), graphene, graphite oxides, multiwalled carbon nanotubes, order mesoporous carbon, and graphitic carbon nitride. Lignocellulosic and biomass wastes are important carbon precursors for low‐cost BC and AC production. This review critically reviews and summarizes the most up‐to‐date research progress in the evolution of SCC for biodiesel production. Systematic discussions and comparisons on the different carbon materials, preparation methods, and sulfonation preparation parameters which directly affect the physicochemical attributes and catalytic performance are provided. The applications and reusability studies of these materials in biodiesel production are also included. Finally, the challenges to be addressed and future prospects of the research direction on the applications of SCC for biodiesel production are discussed.
