“…The direct synthesis of DMC from CO 2 and methanol is an environmentally-benign method for CO 2 utilization, free from the risk of explosion in oxidative carbonylation. In general, organometallic complexes and inorganic bases have been used in the direct synthesis of DMC from CO 2 and methanol at near supercritical conditions [29][30][31]. Jiang et al [31] were more effective for methanol activation than Lewis acid sites.…”

“…In general, organometallic complexes and inorganic bases have been used in the direct synthesis of DMC from CO 2 and methanol at near supercritical conditions [29][30][31]. Jiang et al [31] were more effective for methanol activation than Lewis acid sites. However, this method still remains at the laboratory-scale because the DMC conversion was very low due to the reaction equilibrium limitation and kinetic inertness of CO 2 [16].…”

Due to the increasing emission of carbon dioxide (CO 2 ), the development of fuels and chemicals based on renewable resources has attracted much attention. Bio-oil, as a carbon rich material, has been considered as a feedstock for biodiesel production. In conventional methanol-mediated transesterification of bio-oil for biodiesel production, significant amounts of glycerol are being generated as a byproduct. In order to overcome these issues, dimethyl carbonate (DMC) has been recently used as an alternative acyl acceptor to avoid the generation of glycerol. DMC is an environmentally-benign chemical reagent and reactive solvent due to safety, health, and environmental benefits. Moreover, DMC can be produced from CO 2 . Co-production of biodiesel and chemicals such as glycerol carbonate is possible as the concept of zero-waste utilization of bio-oil. Value-added chemicals can be synthesized using DMC as a reagent. This paper provides a review on the physical and chemical properties of DMC as a solvent, as well as the production methods for DMC. DMC-mediated production of various chemicals and fuels in both chemical and enzymatic processes are discussed together with their pros and cons.

“…The system H 3 PW 12 O 40 /ZrO 2 is active at 373 K, but less selective, such that traces of DME and CO are detected [75] . Among the H 3 PW 12 O 40 /Ce x Ti 1 − x O 2 materials tested, H 3 PW 12 O 40 /Ce 0.1 Ti 0.9 O 2 provided the highest DMC yield, at 443 K, which correlated with the higher number of acid and basic sites.…”

“…It is well known that redox and acid-base properties of POMs can be adjusted by varying the heteroatom, counter anion, and addenda atoms. Moreover, these kinds of materials do not undergo deactivation by water [21][22][23]. Since polyoxometalates are known to be very active catalysts, it would be advantageous to load them on suitable supports, for example, on carbon nanotubes.…”

Carbon nanotubes (CNTs) were functionalized and were then used as supports of Fe 1.5 PMo 12 O 40 (FePMo) Keggin heteropolyanions catalysts. The characterization of the resulting catalysts was investigated by inductively coupled plasma spectrometry (ICP), Fourier transform infrared (FTIR) spectra, X-ray diffraction (XRD), ultraviolet-visible (UV-Vis) light spectroscopy, and transmission electron microscopy (TEM). FTIR and XRD results confirmed that FePMo was bounded on CNTs successfully and the Keggin structure was preserved. Characterization by TEM showed that solids with high FePMo content exhibited aggregation of FePMo in large particles. The as-prepared catalysts were tested in the synthesis of propylene carbonate (PC) from CO 2 and propylene oxide (PO) in a solvent-free reaction and under mild conditions. Effects of various parameters, such as reaction temperature, reaction time, FePMo content on the support, and catalyst loading on the reaction, were investigated. It has been found that CNTs supported FePMo achieved 57.7% PO conversion and 99.0% PC selectivity, whereas unsupported FePMo led only to 8.5% conversion and 48.6% selectivity. The remarkable enhancement of the catalytic activity over the supported catalyst can be attributed mainly to the better dispersion and reactivity of the FePMo catalyst in the supported material.
