“…As depicted in Figure 6a, the Bi 4f spectra of BION indicate two typical peaks of Bi 4f at 158.97 and 164.29 eV, corresponding to the Bi 4f 7/2 and Bi 4f 5/2 states of Bi 3+ . 33,34 The peak of Bi 4f 5/2 is slightly shifted toward higher binding energy after the introduction of I. This can be ascribed to the strong interfacial interactions between BION and BiOI in the IB-3 composite.…”

The construction of S-scheme heterojunctions has proved to be an efficient strategy to overcome the drawbacks of individual photocatalytic materials. Nevertheless, fabricating an intimate interface with strong interfacial coupling in the S-scheme heterojunctions is a challenge. Given that Bi 2 O 2 (OH)(NO 3 ) and BiOI share similar [Bi 2 O 2 ] 2+ unit slices in their crystal structures, we successfully prepare S-scheme BiOI@Bi 2 O 2 (OH)(NO 3 ) heterojunction nanosheets with tight binding by linking [Bi 2 O 2 ] 2+ and I − by the in situ growth of BiOI layers onto the surface of Bi 2 O 2 (OH)(NO 3 ) nanosheets. In comparison to a single Bi 2 O 2 (OH)(NO 3 ) and BiOI nanosheet, the S-scheme heterojunction shows a much increased photocatalytic degradation efficiency for organic pollutants. The significant increase in photocatalytic performance is not only attributed to the formed S-scheme heterojunction, which is capable of establishing an ideal internal electric field (IEF), but also more critically, the carrier separation is greatly facilitated by the tight interfacial interaction between semiconductor nanosheets. This synthetic route provides a constructive idea to be extended to rationally design S-scheme heterojunctions with an intimately bonded interface.

“…This is consistent with the results of photoluminescence (PL) spectra. [28][29][30] Additionally, we employed transient photocurrent measurements and electrochemical impedance spectroscopy (EIS) to examine the behavior of charge separation and migration in the polymer to further compare the photoelectric properties of two photocatalysts. The modified PBNCZ-COO − exhibited a significantly higher transient photocurrent compared to the unmodified PBNCZ (Figure 4d).…”

Advanced oxidation processes (AOPs) using hydroxyl radicals (•OH) as oxidizing agents are a promising technology. Herein, a feasible strategy is developed to initially construct carbazole‐based D‐π‐A type conjugated polymer (PBNCZ) via the oxidative coupling. Additionally, introducing ─COO− through Cyano hydrolysis extends its conjugated structure and improves the energy band structure, which greatly facilitates the generation of •OH as well as the enrichment of pollutants. Detailed experiments and theoretical calculations have proved that the introduction of ─COO− enhances the adsorption of O2 and bisphenol A (BPA), optimizing the reaction path of •OH. Thus, it completely decomposes 10 ppm of BPA within just 10 min, exceeding all previously organic photocatalysts. Meanwhile, the efficiency of photocatalytic H2O2 production by PBNCZ‐COO− reaches 1719.03 µmol h−1 g−1 under visible light. This multifunctional material with high adsorption capacity, photodegradation efficiency, and photocatalytic H2O2 production activity provides a solid foundation for the preparation of organic photocatalysts.
