“…Pyridine-adsorbed FT-IR spectroscopy was performed to investigate the type of acidic site present on Zn 3 In 2 S 6 -C3 and Zn 3 In 2 S 6 , as shown in Figure e. The stretching bands at around 1590 and 1450 cm –1 are ascribed to Lewis (L) acid sites . The vibration bands at 1586 and 1451 cm –1 correspond to the pyridine adsorbed on Lewis acid sites.…”

“…The stretching bands at around 1590 and 1450 cm −1 are ascribed to Lewis (L) acid sites. 48 The vibration bands at 1586 and 1451 cm −1 correspond to the pyridine adsorbed on Lewis acid sites. Obviously, defective Zn 3 In 2 S 6 exhibits stronger Lewis acid sites than the pristine one, which again testifies the merits of surficial acidic−basic sites due to the presence of abundant of sulfur defects.…”

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.

“…The word “catalysis” originates from Greek “κατα” and “λυσισ” which means “down” and “loosening”, respectively. − With the catalyst providing for a rapid and efficient method, the reactions were improved toward a better rate and selectivity at generally gentle conditions . Catalytic technologies have been a fundamental part of modern human advancement. − The Egyptians and the Sumerian utilized catalytic forms to produce alcohol. For centuries, the ancient Greek, classic Roman, and Islamic empires created the agricultural revolution by performing catalysis through controlled ammonia synthesis.…”

Catalysts played a crucial role in advancing modern human civilization, from ancient times to the industrial revolution. Due to high cost and limited availability of traditional catalysts, there is a need to develop cost-effective, high-activity, and nonprecious metal-based electrocatalysts. Metal−organic frameworks (MOFs) have emerged as an ideal candidate for heterogeneous catalysis due to their physicochemical properties, hybrid inorganic/organic structures, uncoordinated metal sites, and accessible organic sections. MOFs are high nanoporous crystalline materials that can be used as catalysts to facilitate polymerization reactions. Their chemical and structural diversity make them effective for various reactions compared to traditional catalysts. MOFs have been applied in gas storage and separation, ion-exchange, drug delivery, luminescence, sensing, nanofilters, water purification, and catalysis. The review focuses on MOF-enabled heterogeneous catalysis for value-added compound production, including alcohol oxidation, olefin oligomerization, and polymerization reactions. MOFs offer tunable porosity, high spatial density, and single-crystal XRD control over catalyst properties. In this review, MOFs were focused on reactions of CO 2 fixation, CO 2 reduction, and photoelectrochemical water splitting. Overall, MOFs have great potential as versatile catalysts for diverse applications in the future.
