“…The imaginary frequency with 294.22 i cm −1 is shown in Figure S26, which had an energy barrier of 4.48 kcal ⋅ mol −1 lower than TS1. Therefore, it is reasonable to think that the ring‐opening process is the speed‐determining step of the entire reaction [48] …”

Herein, the synthesis of a new type of catalyst, SBA−M (Schiff complex of different metal types grafted on SBA‐15) based on a quaternization reaction, is described. Various amounts of ionic liquid were grafted into the pore channels of SBA‐15 using the post‐grafting method, which allowed the ionic liquid to be grafted into the pore channels restrictively. Notably, over six cycles, SBA−Mn (0.2) has been shown to maintain its catalytic activity and stability. In addition, a reaction mechanism for the cycloaddition of CO2 with epoxides based on density‐functional theory is proposed. The cycloaddition reaction of CO2 and epoxides is an efficient way of carbon fixation. It is demonstrated that the metal coordinated with the oxygen atom of the epoxides and that a halogen attacked the carbon of epoxides. Moreover, theoretical calculations and synthesis strategy provide a new approach for CO2 conversion.

“…The catalytic performance of Zr-AZDA is comparable to that of the best homogeneous catalyst (such as NaI • 2H 2 O and Co-Salen), [15,18] and Zr-AZDA also shows higher catalytic activity than most of the reported heterogeneous catalysts (such as Basic-Nano-ZSM-5-Pr-MIM-OH, PIPÀ Bn-Cl, PS-ImHI, MgÀ Al mixed Oxide, MgO nanoparticle, IT-POP-1, CNTammonium salt, MOPÀ Zn-1, CuTrp MOF, Helicate cage, Nu-1000 and Hf-NU-1000). [24,25,[27][28][29]31,36,44,55,64,65] Although the catalytic reaction conditions used in the literatures are versatile, in general the Zr-AZDA catalyst has obvious advantages such as mild reaction conditions, solvent-free at atmospheric pressure (1 atm) and higher catalytic activity.…”

“…To facilitate the process, a number of catalysts have been developed. So far, both homogenous catalysts (such as halogen bond donor catalysts, [9] phosphonium salts, [10,11] ionic liquids, [12][13][14] alkali metal halides [15,16] and metal-salen complexes [17][18][19][20][21][22] ), and heterogeneous catalysts (such as functional zeolite, [23] organosilica, [24] porous ionic polymers, [25] ionic liquid-supported solids, [26,27] metal oxides, [28][29][30] polymers, [31] organic network, [32,33] porous carbons, [34][35][36] bifunctional catalysts [37,38] and metalÀ organic frameworks (MOFs)) have been available for the CO 2 fixation into cyclic carbonates. [39,40] Among these, technically recoverable heterogeneous catalysts such as MOFs have attracted much attention due to their characteristics of high surface area, uniform pore structure and tunable functionalities.…”

Chemical fixation of CO 2 as C1 source at ambient temperature and low pressure is an energy-saving way to make use of the green-house gas, but it still remains a challenge since efficient catalyst with high catalytic active sites is required. Here, a novel monoclinic azo-functionalized Zr-based metalÀ organic polyhedron (Zr-AZDA) has been prepared and applied in CO 2 fixation with epoxides. The inherent azo groups not only endow Zr-AZDA with good solubilization, but also act as basic sites to enrich CO 2 showing efficient synergistic catalysis as confirmed by TPD-CO 2 analysis. XPS results demonstrate that the Zr active sites in Zr-AZDA possess suitable Lewis acidity, which satisfies both substrates activation and products desorption. DFT calculation indicates the energy barrier of the rate-determining step in CO 2 cycloaddition could be reduced remarkably (by ca. 60.9 %) in the presence of Zr-AZDA, which may rationalize the mild and efficient reaction condition employed (80°C and 1 atm of CO 2 ). The work provides an effective multi-functional cooperative method for improvement of CO 2 cycloaddition.
