“…The Cu-Ni alloy supported on molecular sieve were investigated as well [86]. Taking advantage of molecular sieves such as high specific surface area, strong absorbability, good thermal and favorable hydrothermal stability may significantly contribute to the activity of the catalyst.…”

The reaction of carbon dioxide transformation is tremendously interesting in research societies from the viewpoint of carbon resource and also to resolve the environmental problem of carbon dioxide emission. Carbon dioxide (CO 2) is a suitable C1 feedstock which can be converted into a number of valuable fine chemicals. The utilization of CO 2 not only helps to reduce the carbon emission but should also lead to economic benefits, if CO 2 is converted into chemicals for which there are significant demands or have a high added value. The reaction of CO 2 with methanol is one of the pathways to directly synthesize dimethyl carbonate. However, the catalyst is a key factor in the reaction development. Herein, in this review, the focus is made on materials for the catalyzed reaction for the direct synthesis of dimethyl carbonate (DMC) from CO 2 and methanol. The developed catalysts (homogeneous and heterogeneous catalysts) used so far are discussed, together with the respective operating conditions to obtain the optimum catalyst performance. Interesting ideas to allow the direct synthesis of carbonate products from CO 2 with methanol using developed novel catalysts with high performance and efficiency for the economy are offered in this review.

“…Even then, the reactions are preferred at strict conditions and the yield of DMC is relatively low. Though the efforts to these approaches are devoted today, the explorations of advanced heterogeneous catalysts are still regarded as the most effective route [22][23][24]. In particular, CeO 2 based catalysts have been transplanted in the direct synthesis of DMC and show much better catalytic activity as an excellent heterogeneous catalyst [25,26].…”

Ultralong 1D CeO 2 nanowires were synthesized via an advanced solvothermal method, surface reduced under H 2 atmosphere, and first applied in direct synthesis of dimethyl carbonate (DMC) from CO 2 and CH 3 OH. The micro morphologies, physical parameters of nanowires were fully investigated by transmission electron microscopy (TEM), X-ray diffraction (XRD), N 2 adsorption, X-ray photoelectron spectrum (XPS), and temperature-programmed desorption of ammonia/carbon dioxide (NH 3 -TPD/CO 2 -TPD). The effects of surface oxygen vacancy and acidic/alkaline sites on the catalytic activity was explored. After reduction, the acidic/alkaline sites of CeO 2 nanowires can be dramatically improved and evidently raised the catalytic performance. CeO 2 nanowires reduced at 500 • C (CeO 2 _NW_500) exhibited notably superior activity with DMC yield of 16.85 mmol gcat −1 . Furthermore, kinetic insights of initial rate were carried out and the apparent activation energy barrier of CeO 2 _NW_500 catalyst was found to be 41.9 kJ/mol, much tiny than that of CeO 2 _NW catalyst (74.7 KJ/mol).

“…In order to enhance the yield of DMC [28], X.J Wang et al reported the similar Cu-(Ni,V,O)/SiO 2 catalysts with UV irradiation and pushed DMC yield close to 5% [29]. Following the progress of peers, a significant enhancement in catalytic activity and stability was achieved by J. Bian et al [20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35].…”

Alkali-adopted Cu-Ni/diatomite catalysts were designed and used for the direct synthesis of dimethyl carbonate (DMC) from carbon dioxide and methanol. Alkali additives were introduced into Cu-Ni/diatomite catalyst as a promoter because of its lower work function (Ni > Cu > Li > Na > K > Cs) and stronger electron-donating ability. A series of alkali-promoted Cu-Ni/diatomite catalysts were prepared by wetness impregnation method with different kind and different loading of alkali. The synthesized catalysts were fully characterized by means of X-ray diffraction (XRD), scanning electron microscope (SEM), temperature-programmed reduction (TPR), and NH3/CO2-TPD. The experimental results demonstrated that alkali adoption can significantly promote the catalytic activity of Cu–Ni bimetallic catalysts. Under the catalytic reaction conditions of 120 °C and 1.0 MPa; the highest CH3OH conversion of 9.22% with DMC selectivity of 85.9% has been achieved when using 15%(2Cu-Ni) 2%Cs2O/diatomite catalyst (CuO + NiO = 15 wt. %, atomic ratio of Cu/Ni = 2/1, Cs2O = 2 wt. %).
