Maximizing the ionic liquid content and specific surface area in hierarchically nanoporous hypercrosslinked poly(ionic liquid)s towards the efficient conversion of CO<sub>2</sub> into cyclic carbonates

“…As is known, the conversion of CO 2 into value-added cyclic carbonates under mild conditions is an on-going challenge. [19][20][21][22][23][24][25][26][27] The catalytic performances of different catalysts (i.e., MIL-101(Cr), IBCIL, MIL-101 (Cr)/IBCIL physically mixed system, FMOF-IBCIL 0.14 , FMOF-IBCIL 0.19 , and FMOF-IBCIL 0.30 ) in a typical reaction of CO 2 and epichlorohydrin (ECH) at 40 C and atmospheric pressure (1 bar) under same reaction temperature are presented in Figure 3A. A promising chloropropene carbonate (CPC) yield up to 95% (TON = 129.3, Table S4) can be afforded over FMOF-IBCIL 0.19 at 40 C, 1 bar and 24 h in the absence of any cocatalyst.…”

Porous frustrated Lewis pairs (FLPs) have been demonstrated as cutting‐edge heterogeneous catalysts in acidic–basic catalysis, which, yet faces great challenges in synthesis. Herein, we propose a one‐step de novo assembly strategy for constructing porous FLPs by capping monodentate ionic liquids (ILs) on metal clusters during the synthesis of metal–organic frameworks (MOFs). The capping of ILs makes adjacent metal sites on MOFs transforming to coordinatively‐unsaturated metal Lewis acids, producing FLPs containing Lewis basic Cl− ions from ILs and metal sites. The distribution of ILs on the framework of MOFs endows the catalysts with large surface areas (up to 2125 m2 g−1), open channels and good stability. The porous FLPs behave unprecedented activity for atmospheric CO2 activation and coupling with epoxides (25–40°C, 1 bar, without cocatalyst). This de novo assembly strategy exhibits good universality for synthesizing porous FLPs from different kinds of ILs, paving a facile approach for designing high‐efficiency acidic–basic catalysts.

“…Consequently, the capture and utilization of CO 2 has received unprecedented attention in recent years. , Among them, CO 2 cycloaddition reaction holds great promise because of its 100% atomic utilization efficiency and subsequent highly valued cyclic carbonate products. − However, nowadays, industrial routes mainly rely on the traditional TBAB, KI, and other halogen anion nucleophilic reagent homogeneous catalysts, which suffer from low conversion, harsh reaction conditions, and expensive equipment investment . Part of novel catalytic technology based on ionic liquid-based multifunctional homogeneous catalysts is still confronted with high reaction pressure, unsatisfied catalytic efficiency, and homogeneous separation problem. − As a result, developing highly efficient heterogeneous catalysts that can work under mild conditions holds great promise for technological upgrading of CO 2 cycloaddition.…”

Carbon dioxide (CO 2 ) cycloaddition not only produces highly valued cyclic carbonate but also utilizes CO 2 as C1 resources with 100% atomic efficiency. However, traditional catalytic routes still suffer from inferior catalytic efficiency and harsh reaction conditions. Developing multienergy-field catalytic technology with expected efficiency offers great opportunity for satisfied yield under mild conditions. Herein, Zn 3 In 2 S 6 with sulfur vacancies (S v ) was fabricated with the assistance of cetyltrimethylammonium bromide (CTAB), which is further employed for photothermally driven CO 2 cycloaddition first. Photoluminescence spectroscopy and photoelectrochemical characterization demonstrated its superior separation kinetics of photoinduced carriers induced by defect engineering. The temperature-programmed desorption (TPD) technique indicated its excellent Lewis acidity− basicity characters. Due to the combination of above merits from photocatalysis and thermal catalysis, defective Zn 3 In 2 S 6 -S v achieved a yield as high as 73.2% for cyclic carbonate at 80 °C under blue LED illumination within 2 h (apparent quantum yield of 0.468% under illumination of 380 nm monochromatic light at 36 mW•cm −2 ), which is 2.9, 2.0, and 6.9 times higher than that in dark conditions and those of pristine Zn 3 In 2 S 6 and industrial representative tetrabutylammonium bromide (TBAB) thermal-catalysis process under the same conditions, respectively. The synergistic reaction path of photocatalysis and thermal catalysis was discriminated by theoretical calculation. This work provides new insights into the photothermal synergistic catalysis CO 2 cycloaddition with defective ternary metal sulfides.
