“…Therefore, photothermal-synergistic catalysis mode exhibits promising potential for CO 2 conversion reaction. − In previous work, we reported ZnIn 2 S 4 exhibiting superior catalytic activity for CO 2 cycloaddition under photothermal synergism conditions. Photoinduced electrons of ZnIn 2 S 4 would transfer to the surface-adsorbed epoxide reactant to form an epoxide intermediate of electron-rich states, which is beneficial for the subsequent ring-open step of the reactant (RDS) and insertion of CO 2 …”

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.

Developing a highly efficient and environmentally friendly catalytic system for CO2 cycloaddition reactions is an attractive way to achieve carbon neutrality. In this work, tetrabutylammonium iodide (TBAI) and polyethylene glycol (PEG) were used to produce novel deep eutectic solvents (DESs), which could serve as both solvents and catalysts, displaying excellent activity to synthesis styrene carbonates from CO2 and styrene oxide under metal‐free, cocatalyst‐free, solvent‐free and mild conditions. A detailed study was undertaken on the effects of reaction parameters, recyclability, and substrate scope. Additionally, the H‐bond interaction between the substrate and TBAI/PEG200 was thoroughly investigated using FT‐IR and 1H NMR techniques. The synergistic interaction between the two components of the DES, TBAI, and PEG200, may be the key to the high catalytic activity of this system. The tetrabutylammonium iodide‐based system is an innovative strategy for the CO2 cycloaddition with epoxides, achieved by elaborately devising the H‐bonds of DESs to enhance reactivity. This provides a novel green strategy for potential industrial applications.

Developing highly active photocatalysts that can directly utilize clean, cheap, and sustainable solar energy to achieve an efficient carbon dioxide (CO2) cycloaddition reaction under mild reaction conditions (1 bar of CO2) remains a great challenge. In this paper, 2D/2D ZnIn2S4/Zn-NC S-scheme heterojunction composites were constructed by the in situ growth of layered ZnIn2S4 on the surface of two-dimensional (2D) ZIF-L-derived Znδ+ (0 ≤ δ ≤ 2) and N codoped carbon skeletons (Zn-NC-T) via a low-temperature solvothermal method. The optimized ZnIn2S4/Zn-NC-T photocatalysts exhibited favorable photocatalytic CO2 cycloaddition performance, and the yield of cyclic carbonate reached about 98.8% under 10 mmol epoxides reactant, 1 bar CO2 pressure, and full-spectrum irradiation for 4 h. The favorable photocatalytic performance is attributed to the efficient photothermal conversion and effective separation of photogenerated carriers induced by the carbon matrix and heterojunctions, respectively. In addition, the stability of the heterojunction structure and activity were demonstrated through cyclic experiments. Furthermore, the possible mechanism of S-scheme heterojunction photocatalytic CO2 cycloaddition is proposed through electron paramagnetic resonance (EPR) spectra, cyclic voltammetry (CV) experiments, and quenching experiments. The mechanism analysis proved that light irradiation is conducive to the transfer of photogenerated electrons from the conduction band of ZnIn2S4 to epoxides, promoting the formation of ring-opening intermediates, and photogenerated holes may promote the coordination and polarization of adsorbed epoxides. This work not only prepared an S-scheme heterojunction catalyst with excellent photocatalytic CO2 cycloaddition performance but also provided new insights for the rational design of heterojunction catalysts for photocatalytic CO2 cycloaddition.
