“…CdS QDs have excellent visible light absorption properties, and Li et al successfully prepared 0D-2D CdS/WO 3 S-scheme heterojunction photocatalysts by hydrothermal method, and 2D WO 3 nanosheets are able to boost the dispersion of CdS quantum dots. 139 The CdS/WO 3 composites showed good CO 2 photoreduction ability, with yields of 64.7 and 2.3 μmolg −1 h −1 for CO and CH 4 , respectively. The high yield is attributed to the enhanced dispersion of CdS QDs by 2D WO 3 , which enhances the efficiency of CO 2 adsorption, and the synergistic effect with the S-scheme heterojunction to maximize the CO 2 reduction efficiency.…”

Photocatalytic CO2 reduction (PCO2RR) is regarded as a promising means to mitigate the effects of climate change and current energy shortage. However, photocatalysis is not very effective because of the rapid recombination of photogenerated electron–hole pairs. S-scheme heterojunctions can effectively separate photogenerated carriers and significantly improve the redox ability of photocatalysts. In recent years, S-scheme heterojunction photocatalysts have become a popular topic of research because of their superior photocatalytic performance. This review examines the recent research advancements in S-scheme heterojunction photocatalysts. First, the principle of PCO2RR is briefly introduced. Various types of heterojunctions are introduced, the charge transfer mechanisms and characterization methods of S-scheme heterojunctions are described, and the applications of metal oxides, metal sulfides, and other S-scheme photocatalysts in CO2 reduction are discussed and reviewed, respectively. In conclusion, the limitations and prospective directions of S-scheme heterojunction photocatalysts in CO2 photoreduction are discussed to provide direction for the design of high-performance S-scheme heterojunction photocatalysts.

“…These strategies include changing the morphology of CdS from bulk material to nanospheres (either mesoporous or nanorods structures), [18][19][20][21][22] and doping with metal/non-metal elements such as Ag, graphene quantum dots (GQDs), g-C 3 N 4 , [23][24][25] and other semiconductors like TiO 2 , WO 3 , MoS 2 . [26][27][28] Among these modications, GQDs are zero-dimensional carbon nanomaterials that are low cost, nontoxic, have excellent optical performance, are biocompatible, and amenable to surface modications. 29 Furthermore, GQDs show very strong visible light absorption properties, have tunable bandgaps, and possess superior photo-stability.…”

“…Therefore, selection of a suitable RP and OP with specific nanostructures is the key step to the development of S-scheme nanocatalysts in the CO 2 photoreduction process. 10 As an excellent photocatalytic material, ZnIn 2 S 4 has been widely researched in the fields of photocatalytic degradation, photocatalytic hydrogen, and so on, due to its great visiblelight responsiveness, tight band gap width (E g ), high physical and chemical stability, and easy synthesis. 11,12 ZnIn 2 S 4 is a great candidate for the RP material because of its suitable conduction band position and appropriate width of the band gap (E conductionband , E CB ≈ −1 V, E g ≈ 2.3 eV).…”

The nanostructure of the photocatalyst plays a crucial role in determining its catalytic ability. In this paper, a 2D/2D WO 3 /ZnIn 2 S 4 Sscheme heterojunction was successfully prepared through a simple hydrogen reaction. Under UV−vis light irradiation, the yield of CO in the CO 2 photoreduction process using WO 3 /ZnIn 2 S 4 as the catalyst reached about 44.61 μmol•g −1 , which was about 3.9 times higher than that obtained with ZnIn 2 S 4 alone. Cycling experiments demonstrated that the binary composite exhibited excellent photocatalytic activity and material stability. Photoelectrochemical measurements revealed that the 2D/2D WO 3 /ZnIn 2 S 4 Sscheme heterojunction significantly enhanced the separation efficiency of photogenerated carriers and effectively improved the redox ability of the photocatalyst. Density functional theory calculations were employed to analyze the electron transfer pathways and the formation of the built-in electric field at the 2D/2D WO 3 /ZnIn 2 S 4 interface, confirming that the heterojunction structure accelerated the transfer of photogenerated electrons from WO 3 to ZnIn 2 S 4 . The CO 2 photoreduction process was further investigated by in situ FTIR. Finally, a possible S-scheme electron transfer mechanism at the 2D−2D WO 3 /ZnIn 2 S 4 interface during the CO 2 photoreduction reaction was proposed and discussed.
