“…Fourier-transform infrared spectroscopy (FT-IR) was conducted to explore the surface function group of catalysts. Doublet evident absorption peaks located at 2915 and 2843 cm –1 for Zn 3 In 2 S 6 -C3 (Figure c) can be ascribed to methylene C–H asymmetric and symmetric stretching vibrations, respectively . Meanwhile, absorption peaks at ∼1618 and ∼1426 cm –1 are attributed to absorbed H 2 O or hydroxyl .…”

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.

“…Among many photocatalysts, ZnIn 2 S 4 , as a ternary metalsulfur compound semiconductor catalyst with a typical layer structure, has a narrower band gap compared with traditional oxide photocatalysts such as TiO 2 , [2][3] ZnO, [4][5][6][7] ZrO 2 , [8][9][10][11] etc. Compared with binary metal-sulfur semiconductor photocatalysts such as CdS, [12][13][14] CuS, [15][16][17][18][19] and ZnS, [20][21][22][23] ZnIn 2 S 4 is greener in the photocatalytic reaction process without generating toxic ions and more straightforward to prepare compared with other ternary metal-sulfur compounds such as ZnCdS, [24][25][26][27] Zn 3 In 2 S 6 , [28][29][30][31] etc., while attracting the attention of many related workers by its unique photoelectric properties and catalytic characteristics. ZnIn 2 S 4 is an n-type semiconductor with three different crystal morphologies, including cubic phase, hexagonal phase, and rhombic phase, [32] among which the two crystalline forms of cubic phase and hexagonal phase are more common in photocatalytic experiments.…”

As a green technology, photocatalytic reduction of CO2 can reduce CO2 into reusable carbon‐based fuels and alleviate environmental and energy problems to a certain extent. However, traditional photocatalytic materials have irreparable defects that limit their applications in photocatalysis, and it becomes a great challenge to find an efficient photocatalytic material. ZnIn2S4, a new photocatalyst, is widely used in photocatalysis because of its layered structure, tunable band gap, excellent photoelectric properties, and catalytic characteristics, and it is also favored by a wide range of scientific researchers due to its stable chemical properties. The construction of heterojunctions can further increase the photocatalytic ability of ZnIn2S4. This review introduces the electron transfer mechanism of different ZnIn2S4‐based heterojunctions in the photocatalytic process and its recent research progress in photocatalytic CO2 reduction applications. Finally, an outlook on constructing ZnIn2S4‐based heterojunctions and their development prospects is presented.

“…In contrast to systems that preferentially photocatalyze the formation of aldehydes, highly efficient photocatalysts for producing C–C coupling products via preferential activation of C–H bonds are rare. , For instance, ternary metal sulfides, including zinc indium sulfide (ZnInS) materials, were introduced as effective photocatalysts for the transformation of C–C coupling products from aromatic alcohols. The development of “smart” photocatalysts is critical to achieve high phototransformation efficiencies with high selectivity toward C–C coupling products in the transformation of aromatic alcohol.…”

Existing methods for the photocatalytic transformation of aromatic alcohols to value-added products via C−C cross-coupling are inefficient and insufficiently selective. Herein, a series of cadmium sulfide nanowires (CdS NWs) loaded with Ag 2 S (denoted as Ag 2 S@CdS NWs) are constructed via a simple Ag + exchange protocol for the photocatalytic transformation of benzyl alcohol. We successfully demonstrated that the selectivity toward specific products in the photocatalytic transformation of benzyl alcohol over Ag +exchanged CdS NWs is controlled by varying the amount of exchanged Ag + ions. Notably, the product of the photocatalytic reaction was dependent on the amount of Ag + ions exchanged: with a Ag + exchange of <5 mol %, the C−C coupling product was obtained with >90% selectivity and >95% transformation yield owing to photoinduced electron transfer from the conduction band of CdS to Ag 2 S. Conversely, with a Ag + exchange of >7 mol %, a cocatalyst in which Ag 2 S and Ag are mixed was produced, and benzaldehyde was obtained with >90% selectivity and >90% transformation yield because of photoinduced hole transfer from the valence band of CdS to Ag 2 S/Ag. This study proves that Ag 2 S@CdS NWs can be used as a basis for the development of heterojunction photocatalysts for the conversion of aromatic alcohols into value-added products via C− C cross-coupling reactions or photooxidation toward aromatic aldehyde.
