“…In addition, the band at about 1360 cm −1 can be attributed to absorbed CO 3 2− , 35 The absorption peaks at 1050 cm −1 and 768 cm −1 can be attributed to the vibration of metal hydroxyl groups (M-OH), and the absorption peak at 505 cm −1 is associated with the Cu-O-Fe stretching mode. [35][36][37] Fig. 1c shows the N 2 adsorption/desorption curves of CuFe-LDHs, which matched well with the H3-type hysteresis loop, meaning that CuFe-LDHs are mesoporous materials.…”

“…As shown in Figure 3b, Table S1 (Supporting Information), the N 2 adsorption‐desorption isotherms before and after incorporating PM6:IDT6CN‐M:IDT8CN‐M onto CSC exhibited typical IV type isotherms with a characteristic H 3 hysteresis loop, indicating the presence of mesoporous pores in the samples. [ 37 ] The specific surface area of CSC@PM6:IDT6CN‐M:IDT8CN‐M (1283.02 m 2 g −1 ) was comparatively smaller than that of pure CSC (1599.52 m 2 g −1 ). Based on the BET analysis results, it can be inferred that the specific surface area of CSC decreased after loading PM6:IDT6CN‐M:IDT8CN‐M, while the pore size remained relatively unchanged, thereby retaining its structural characteristics of microporous and mesoporous feature, and the micropore size distribution of the catalyst should be shown in Figure 3c.…”

Converting carbon dioxide (CO2) into high‐value chemicals using solar energy remains a formidable challenge. In this study, the CSC@PM6:IDT6CN‐M:IDT8CN‐M non‐fullerene small‐molecule organic semiconductor is designed with highly efficient electron donor‐acceptor (D‐A) interface for photocatalytic reduction of CO2. Atomic Force Microscope and Transmission Electron Microscope images confirmed the formation of an interpenetrating fibrillar network after combination of donor and acceptor. The CO yield from the CSC@PM6:IDT6CN‐M:IDT8CN‐M reached 1346 µmol g−1 h−1, surpassing those of numerous reported inorganic photocatalysts. The D‐A structure effectively facilitated charge separation to enable electrons transfer from the PM6 to IDT6CN‐M:IDT8CN‐M. Meanwhile, attributing to the dipole moments of the strong intermolecular interactions between IDT6CN‐M and IDT8CN‐M, the intermolecular forces are enhanced, and laminar stacking and π‐π stacking are strengthened, thereby reinforcing energy transfer between acceptor molecules and significantly enhanced charge separation. Moreover, the strong internal electric field in the D‐A interface enhanced the excited state lifetime of PM6:IDT6CN‐M:IDT8CN‐M. In situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) analysis demonstrated that carboxylate (COOH*) is the predominant intermediate during CO2 reduction, and possible pathways of CO2 reduction to CO are deduced. This study presents a novel approach for designing materials with D‐A interface to achieve high photocatalytic activity.

“…However, it is noteworthy that the anode’s enhancement contributes marginally to the overall system performance. − On the one hand, this is due to the limited extent of the increase in photocurrent at the photoanode; on the other hand, it is because the electrons migrating to the cathode cannot be rapidly consumed due to slow kinetics and other reasons, thereby becoming the bottleneck that restricts the entire process. Consequently, there has been a shift in research focus toward the design and selection of cathodes. − For instance, Sun et al developed a novel Au/Fe-modified copper foam cathode, which effectively produced H 2 O 2 , leading to efficient degradation of organic pollutants and concurrent power generation . Su et al fabricated an iron-doped NiCo 2 S 4 (NCS) cathode, which demonstrated a high efficiency in degrading tetracycline .…”

In this study, ZnIn 2 S 4 nanoflowers were deposited on the surface of NiCo 2 S 4 hexahedrons using nickel foam (NF) as the substrate, employing a facile two-step solvothermal approach. The fabricated ZnIn 2 S 4 /NiCo 2 S 4 /NF cathode, in conjunction with a TiO 2 − Si solar panel integrated photoanode, was employed to assemble a photocatalytic fuel cell (PFC) aimed at treating tetracycline (TC) in wastewater and simultaneously generating electricity. The results reveal that the PFC featuring the ZnIn 2 S 4 /NiCo 2 S 4 cathode significantly enhanced the yield of H 2 O 2 (260 μmol/L), which was 3.3 times higher than that of the PFC with the NiCo 2 S 4 cathode (78 μmol/L). The constructed PFC exhibits the capability to function across a broad pH range of 3−11, achieving its peak degradation efficiency at pH 7. Under optimized conditions, the system exhibited a high TC removal efficiency of 96.7% within 60 min, alongside remarkable electricity generation, achieving a short-circuit current density of 0.69 mA cm −2 and a maximum power density of 0.53 mW cm −2 . Quenching experiments and electron paramagnetic resonance analyses indicate that 1 O 2 ,• O 2− , • OH, and h + species are generated in the system, with • O 2 and 1 O 2 primarily contributing to the TC degradation process. This research offers new perspectives on the strategic design of cathodes in PFC systems for the effective degradation of organic pollutants and concurrent electricity generation.
