Synthesis of Propylene Carbonate from Carbon Dioxide through High Activity of Magnesium Oxide

Single-molecule magnet behaviour and catalytic properties of tetrahedral Co(ii) complexes bearing chloride and 1,2-disubstituted benzimidazole as ligands

“…Due to the inert nature of carbon dioxide, a catalyst is generally required to turn its chemical transformation possible. Numerous homogeneous and heterogeneous catalysts have been developed for this purpose, such as ionic liquids, 12–14 organocatalysts and other metal-free catalysts, 15–17 metal oxides and hydroxides, 18–21 metal–organic frameworks, 22,23 and metal complexes. 24–27…”

“…[9][10][11] Due to the inert nature of carbon dioxide, a catalyst is generally required to turn its chemical transformation possible. Numerous homogeneous and heterogeneous catalysts have been developed for this purpose, such as ionic liquids, [12][13][14] organocatalysts and other metal-free catalysts, [15][16][17] metal oxides and hydroxides, [18][19][20][21] metal-organic frameworks, 22,23 and metal complexes. [24][25][26][27] Our group has reported an active zinc(II) compound bearing 1,2-disubstituted-benzimidazole ligands to catalyse the transformation of several epoxides to cyclic carbonates.…”

Mining industrial materials as heterogeneous catalyst for high value‐added cyclic carbonates production from CO2

“…Some recent examples found in the literature suggest the huge potential of porous MgO material in sustainable heterogeneous catalyst that can be readily separated from a mixture to be recycled. [22][23][24] However, the development of high catalytic activity, selective, stable, industrial readily available and reusable catalysts for this cycloaddition reaction is still a challenge. According to European Commission research, global raw material extraction has grown 14 times, with the sharpest increase in industrial minerals at 45 times.…”

“…Since the publication in 1997 by Yano and coworkers 22 of the cycloaddition reaction between propylene oxide and CO 2 using a stoichiometric amount of MgO, this catalyst has been studied as a nontoxic, recyclable, and cheap catalyst for CO 2 fixation to obtain cyclic carbonates as valuable products. Some recent examples found in the literature suggest the huge potential of porous MgO material in sustainable heterogeneous catalyst that can be readily separated from a mixture to be recycled 22–24 . However, the development of high catalytic activity, selective, stable, industrial readily available and reusable catalysts for this cycloaddition reaction is still a challenge.…”
