“…Although a few complexes of phosphine substituted bi-or poly-dentates have found specific catalytic applications, e.g. zinc complexes in olefin oxide polymerisations [48][49][50], it seems unlikely that many catalytic applications will emerge. The major area of application lies in the chemistry related to III-V semi-conductor materials, which has been described in detail in excellent reviews.…”

“…The homogeneous catalysts are alkali metal salts [3,4], organotin or organoantimony compounds [5,6], ionic liquids or onium salts [7][8][9][10][11][12][13][14][15][16][17][18][19][20], and transition metal complexes [21][22][23][24][25][26][27][28][29][30][31]. For heterogeneous interactions, metal oxides [32][33][34], zeolites [35,36], smectites [37,38], and polyoxometalate [39,40] are used.…”

3-(2-hydroxyl-ethyl)-1-propylimidazolium bromide (HEPIMBr) was immobilized onto SBA-15, Al-SBA-15 mesoporous molecular sieves and SiO 2 by chemical grafting method. The materials were characterized and used as catalysts for solvent-free synthesis of cyclic carbonates from CO 2 and epoxides under relatively mild conditions. Among them, the HEPIMBr immobilized on SBA-15 performs the best, showing carbonate selectivity and yield of ca. 100% (120°C, 2.0 MPa, 2 h). The catalyst is thermally stable and shows good reusability. Based on the experimental results, a plausible reaction mechanism has been proposed for the catalytic reaction.

“…In the past decades, numerous catalysts have been studied for the cycloaddition reaction , e.g., metallic complexes [4][5][6][7], phosphines [8,9], organic bases [10][11][12], ionic liquids [13][14][15][16], metal oxides [17][18][19], modified molecular sieves [20][21][22][23][24] and smectite [25], and supported catalysts [26][27][28][29][30], etc. However, most of the high-efficiency ones are homogeneous catalysts, and the disadvantages are the high cost for catalysts fabrication (e.g., metallic complexes) and product separation.…”

“…It was reported that the Zn-containing catalysts showed high efficiency for the cycloaddition reaction, and Zn 2? was regarded as essential for epoxide activation [6,7,15,33,34]. Herein, we report the fabrication and catalytic performance of the Zn-Al composite oxides that were modified by alkaline earth metals.…”

Synthesis of Propylene Carbonate from Carbon Dioxide and Propylene Oxide Using Zn-Mg-Al Composite Oxide as High-efficiency Catalyst

A series of Zn-Al composite oxides that were modified with alkaline earth metals, Zn-M-Al-O (M = Mg, Ca, Sr, and Ba) were fabricated via calcination of the corresponding hydrotalcite precursors, and evaluated as catalysts for the synthesis of propylene carbonate (PC) from CO 2 and propylene oxide. Among the Zn-M-Al-O catalysts, Zn-Mg-Al-O (Zn/Mg = 4.0, pH = 10, without hydrothermal treatment) is the best in performance, showing PC selectivity of 99.2% and yield of 88.8% (140°C, 12 h). Furthermore, the Zn-Mg-Al-O catalyst can be readily reused and recycled without any loss of activity in a test of five cycles. Through detailed studies of the basic nature of the Zn-M-Al-O catalysts, it was found that a moderate basicity (6.1 B H 0 \ 8.9) is beneficial to the cycloaddition reaction. The NH 3 -and CO 2 -TPD results also indicate that the Zn-Mg-Al-O catalyst has acid-base bifunctional properties, and a reaction mechanism is proposed.
