“…7c). Taking the known binding energy of binary vanadium oxides into consideration, it was consistent with the material’s formal valence of + 5 [17]. The state of titanium is tetravalent titanium dioxide and the state of vanadium is vanadium pentoxide, as indicated by the standard spectra.…”

“…The reported heterogeneous catalysts include single or composite oxides [5], zeolites [6], hydrotalcite-like compounds [7], and heteropoly compounds [8]. Tong et al found that V 2 O 5 had the excellent activity for the transesterification of DMC with phenol [9]. Other groups presented that Pb 3 O 4 /ZnO, PbO/MgO, and V 2 O 5 as catalysts contributed to the synthesis of DPC [10].…”

A series of TiO2-V2O5-MCM-41 molecular sieve catalysts were prepared by the impregnation method. The prepared catalysts were characterized by different techniques including X-ray diffraction, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, and N2 adsorption–desorption. These catalysts were applied in the catalytic synthesis of diphenyl carbonate (DPC) by the transesterification of dimethyl carbonate (DMC) with phenol. The synthesis results indicated that the catalysts possessed the high specific surface area and large pore volume and included titanium with four ligands. Due to the vanadium introduction into Ti-MCM-41, the catalytic activity was promoted, by-products were reduced, and the catalytic activity and stability of the catalyst were significantly improved. With 10%V-20%Ti-MCM-41 catalyst, the optimal synthesis results including the conversion rate of DMC of 33.88%, the selectivity of DPC of 35.84%, and the yield of DPC of 12.14% were obtained.

“…Among linear carbonates the most important are dimethylcarbonate (DMC), diphenylcarbonate (DPC) and diethylcarbonate (DEC). DMC is used in the chemical industry as monomer for polymers, in transesterification reactions for the production of other carbonates such as diphenylcarbonate and others, as alkylating or carboxylating agent . It is also used in the agrochemical and pharmaceutical industry for the production of chemicals or in product formulation.…”

CO2 is considered to play a key role in an eventual climate change, due to its accumulation in the atmosphere. The control of its emission represents a challenging task that requires new ideas and new technologies. The use of perennial energy sources and renewable fuels instead of fossil fuels and the conversion of CO2 into useful products are receiving increased attention. The utilization of CO2 as a raw material for the synthesis of chemicals and fuels is an area in which scientists and industrialists are much involved: the implementation of such technology on a large scale would allow a change from a linear use of fossil carbon to its cyclic use, mimicking Nature. In this paper the use of CO2 as building block is discussed. CO2 can replace toxic species such as phosgene in low energy processes, or can be used as source of carbon for the synthesis of energy products. The reactions with dihydrogen, alcohols, epoxides, amines, olefins, dienes, and other unsaturated hydrocarbons are discussed, under various reaction conditions, using metal systems or enzymes as catalysts. The formation of products such as formic acid and its esters, formamides, methanol, dimethyl carbonate, alkylene carbonates, carbamic acid esters, lactones, carboxylic acids, and polycarbonates, is described. The factors that have limited so far the conversion of large volumes of CO2 are analyzed and options for large‐scale CO2 catalytic conversion into chemicals and fuels are discussed. Both homogeneous and heterogeneous catalysts are considered and the pros and cons of their use highlighted. © 2013 Society of Chemical Industry

“…Our group was devoted to developing homogeneous and heterogeneous catalysts for the transesterification of DMC and phenol [29][30][31][32][33][34]. Heteropoly compounds (HPCs) as environmentally-benign catalysts were widely used in homogeneous and heterogeneous catalysis due to their special hierarchical structure and physicochemical properties [35].…”
