“…Addressing these issues hinges on the transformation of homogeneous catalysis into heterogeneous catalysis. At present, the main heterogeneous catalysts for CO 2 cycloaddition are metal–organic frameworks (MOFs), ,− porous organic polymers, , supported ionic liquids, ,, poly(ionic liquids), − and carbon materials. , Among them, the supported ionic liquid was considered to be an important direction of cycloaddition catalyst research in the future. This method mainly combines highly efficient homogeneous ionic liquid with carriers to achieve heterogeneity.…”

In this study, tetrabutylammonium bromide (TBAB) with a cationic radius of 4.94 Å was encapsulated in ZIF-8 with a pore size of 3.4 Å by a one-step method. The TBAB@ZIF-8 catalyst showed superior catalytic activity on the reaction of CO2 with propylene oxide (PO) than TBAB and the zeolitic imidazolate framework, respectively, showing a synergistic effect. The synergist effect was related with the compensation effect between the adsorption of CO2 and the loop-opening of PO, where ZIF-8 provided the active sites for CO2 adsorption and Br– in TBAB promoted the opening of the loop of PO. The catalytic performance of TBAB@ZIF-8 illustrated a volcano curve with the increase of the TBAB content. The addition of TBAB could have resulted in a positive effect on the loop-opening of PO. However, excessive TBAB hindered mass transfer and reduced the CO2 adsorption of ZIF-8, which was certified by the CO2 adsorption test. Diffuse reflectance infrared Fourier transform spectroscopy results showed that TBAB@ZIF-8 catalysts proceed in a new reaction pathway and that the rate-determining step of the reaction was the opening of the loop of PO. These results provided a guideline for the development of immobilization of homogeneous catalysts for CO2 fixation.

Heterogeneous single‐metal‐site catalysts (SMSCs) have received increasing attention due to their outstanding stability and recyclability. In this work, a novel Ir‐based SMSC was successfully constructed through the coordination polymerization between zirconium and triphenylphosphine derivatives with carboxyl functional groups for efficient propylene hydroformylation with CO. The Ir‐based SMSC reported here can achieve a turnover number of over 20,000 (being 7.3 times higher than the most effective Ir‐base catalyst to date) with 99% selectivity and 56% yield for aldehyde. Besides, it represents the first example with a higher selectivity of isobutyraldehyde than n‐butyraldehyde (i.e., n/i = 0.62) among the reported Ir‐based catalysts. The Ir‐based SMSC can be easily reused for at least 10 cycles without losing its reactivity, whereas the homogeneous monomer catalyst quickly loses its reactivity after the second cycle. Furthermore, the catalytic mechanism of Ir‐based SMSC is proposed based on reaction explorations and in situ co‐adsorption tests by the method of diffuse reflectance infrared Fourier transform spectroscopy, which has also been revealed by theoretical calculations. This work provides a novel insight into the design of SMSCs with great potential for application in the hydroformylation field.
