“…Moreover, some new peaks appeared in the CCR-500 spectrum. The peaks at 881 cm -1 and 699 cm -1 came from the vibration of carbonate (Wang et al 2019). The peak at 1061 cm -1 can be ascribed to phosphate (Shikhaliyev et al 2018).…”

“…Given the negligible cost of the feedstock, the direct use of waste materials rather than chemical reagents to prepare the base catalyst in transesterification reactions has drawn increased attention. Some waste materials have been used as the feedstock for preparing base catalysts, including eggshell (Gupta et al 2018), chicken manure (Jung et al 2017), fish waste (Shikhaliyev et al 2018), marine barnacle (Manaf et al 2018), disposable diapers (Wang et al 2019), and oil palm empty fruit bunch (Okoye et al 2019). Therefore, utilizing waste materials to prepare a base catalyst can allow for new ways to synthesize GC using the transesterification of glycerol with DMC.…”

Corncob was calcined within a temperature range of 300 °C to 700 °C to prepare a series of corncob residue catalysts for the transesterification of glycerol with dimethyl carbonate (DMC) to synthesize glycerol carbonate (GC). Among the catalysts, the corncob residue catalyst obtained through calcination of corncob at 500 °C (CCR-500) showed a relatively high basicity and satisfactory catalytic activity. The structural investigation results indicated that CCR-500 was composed of carbon material and some alkaline mineral salts. Using CCR-500 as the catalyst, a glycerol conversion of 98.1% and a GC yield of 94.1% were achieved when the reaction was performed at 80 °C for 90 min, with a catalyst amount of 3 wt% and glycerol to DMC molar ratio of 1:3. The comparison of CCR-500 with the reported catalysts indicated that the CCR-500 was a low-cost, high-active, and easily-accessible catalyst for the transesterification of glycerol with DMC.

This Review presents current knowledge, recent results, and challenges for the future in heterogeneous oxidation catalysis in liquid and gaseous phases on solid metal oxide catalysts. Metal oxides that are used as catalysts and their main structures and properties are summarized, as well as their catalytic properties in selective and total oxidation reactions, which were studied intensively, experimentally and theoretically, by Professor Jerzy Haber during his scientific life. Some emphasis is placed on the classical and unusual catalyst activation procedures for improving catalytic properties for better efficiency. For a more sustainable world, several examples are given of the oxidation of biomass derivatives to synthesize valuable chemicals and of other applications of metal oxides, such as depollution, photocatalysis, hydrogen production and fuel‐cell components. The importance of metal oxide catalysis in environmental and green chemistry and sustainability is discussed, and challenges for the future are considered.

“…Carbonate glycerol (GC) is widely used in food, medicine, plastics, military, new materials and new energy as a special bio-based chemical with high boiling point, low freezing point, low volatility, low flammability and strong polarity [ 9 ]. The transesterification of glycerol with dimethyl carbonate (DMC) over basic catalysts is considered to be an effective method for GC synthesis under mild conditions [ 10 ]. The only reaction byproduct methanol is easily separated from the product mixture.…”

Ca-Mg-Al hydrotalcites were prepared by coprecipitation from Type S95 steel slag of Shanghai Baosteel Group as supports of ionic liquid in this paper. Five basic ionic liquids [Bmim][CH3COO], [Bmim][HCOO], [Bmim]OH, [Bmim]Br and ChOH were prepared and their catalytic performance on the synthesis of glycerol carbonate by transesterification between dimethyl carbonate and glycerol was investigated. The characterization results indicated that [Bmim]OH is the best ionic liquid (IL) for the transesterification reaction of glycerol carbonate. The hydrotalcites before and after intercalation by ionic liquid were characterized by XRD, FTIR, SEM, EDS and the IL were characterized by FT-IR, 13C-NMR and basicity determination via the Hammett method. The analysis results implied that the dispersion of [Bmim]OH in hydrotalcites reduced the alkali density appropriately and facilitated the generation of glycerol carbonate. The yield of glycerol carbonate and the conversion rate of glycerol reached 95.0% and 96.1%, respectively, when the molar ratio of dimethyl carbonate and glycerol was 3:1, the catalyst dosage was 3 wt%, the reaction temperature was 75 °C and the reaction time was 120 min. The layered structure of hydrotalcites increased the stability of ionic liquid intercalated in carriers, thus the glycerol conversion and the GC yield still remained 91.9% and 90.5% in the fifth reaction cycle.
