“…As illustrated in Figure S1, for the pristine C−Si and C−M−Si catalysts, the structural integrity of C−Si remained practically unchanged upon incorporation of the metal species. Both C−Si and C−M−Si substrates showed nearly identical single, broad XRD peak over the 2 θ range of 11–35°, resembling that of amorphous carbon structure [33–35] . The main diffraction peak at 2 θ =26.5° and the weak shouldering peak at ca.…”

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.

“…5 Assuming the same composition as potato starch, PPW would contain 73-79% amylopectin and 12-27% amylose. 6 The starch can be utilized for various purposes such as ethanol fermentation, 7 novel material synthesis, 8 and enzyme production, 9 despite the poor water solubility, easy retrogradation after gelatinization, and high gelatinization temperature of starch. 10 Another potential application of PPW is the production of cationic starch flocculants for wastewater treatment.…”

“…Although these methods are efficient for biodiesel production, the use of homogenous chemical catalysts (e.g., NaOH, KOH, and H 2 SO 4 ) complicates product purification and wastewater treatment [9]. Hence, various solid acid and alkali catalysts have been proposed to simplify biodiesel production because these solid catalysts can be easily recovered and reused [10][11][12]. However, heterogeneous catalytic reactions have a relatively low reaction rate because of mass transfer limitations [10].…”

Electrolysis is a promising approach for biodiesel production. However, low electrical conductivity of a reaction mixture results in a low reaction rate. Thus, this study developed a novel catalyst-free electrolysis process using an ionic liquid as a supporting electrolyte for biodiesel production. Various ionic liquids were assessed, and 1-ethyl-3-methylimidazolium chloride ([Emim]Cl) exhibited the highest electrical conductivity (4.59 mS/cm) and the best electrolytic performance for transesterification. Electrolysis in the presence of [Emim]Cl was subsequently optimized using response surface methodology to maximize biodiesel yield. A maximum biodiesel yield of 97.76% was obtained under the following optimal reaction conditions: electrolysis voltage, 19.42 V; [Emim]Cl amount, 4.43% ( w / w ); water content, 1.62% ( w / w ); methanol to oil molar ratio, 26.38 : 1; and reaction time, 1 h. Notably, [Emim]Cl could be efficiently reused for at least three cycles with a corresponding biodiesel yield of 94.81%. Moreover, the properties of the synthesized biodiesel complied with EN and ASTM standards. The findings of this study indicate that catalyst-free electrolysis using [Emim]Cl as a supporting electrolyte is an eco-friendly and efficient method for biodiesel production.
