“…There are three peaks in Figure 5d of O 1s, which are matched with the crystal lattice O atoms (Bi─O) and, the O atom in the ligand of MOFs and other components (such as ─OH and H 2 O) adsorbed on the surface of catalyst. [ 38,51 ] Compared with O 1s of BiOBr and MgBTC, BM‐55 has a slight shift to increase binding energy, which can be attributed to the strong chemical bonding between BiOBr and MgBTC. From the spectrum of C 1s (Figure 5e), there are three peaks at 288.2, 285.9, and 284.5 eV, which can be ascribed to C═O, C─C, and C═C bonds of H 3 BTC.…”

“…The M‐S plots calculated at the frequency of 1000 Hz were shown in Figure 9, the position slope of the plot reveals that BM‐55 is an n ‐type semi‐conductor characteristic. [ 44,51 ] The potential of BiOBr, MgBTC, and BM‐55 relative to the saturated calomel electrode is 0.21, −0.34, and −0.23 eV (vs. SCE), respectively. For n ‐type semiconductors, the conduction‐band potential was ca.…”

A series of binary composite photo‐catalyst BiOBr/MgBTC (the ligand of MgBTC is 1, 3, 5‐benzenetricarboxylate = H3BTC) with different content of BiOBr have been designed and used to degrade the traditional dye rhodamine B (RhB). As‐prepared binary composites have been first obtained via a simple hydrothermal system and subsequently deposited onto the BiOBr substrates. The composites exhibited better catalytic performance compared with the pristine BiOBr, and the performance of BM‐55 (synthesized by 0.55 mmol BiOBr and 0.45 mmol MgCl2•6H2O) was the most efficient and its removal rate of RhB can reach 98.3% within 60 min. The composite photo catalyst was characterized by X‐ray diffraction (XRD), infrared (IR), scanning electron microscope (SEM), X‐ray photoelectron spectroscopy (XPS), diffuse reflectance spectroscopy (DRS), photoluminescence (PL), and electrochemical impedance spectroscopy (EIS), respectively. In the free radical trapping experiments, it can be seen that the main photo‐catalytic active species are superoxide radicals (•O2−) and holes (h+). This work can provide considerable opportunities to the development of various metal–organic frameworks (MOF)‐based visible light photo‐catalysts and modified 2D bismuth ox halide materials (BiOX) for use in environmental cleaning application.

“…However, the peak at 510 cm À1 , attributed to Bi-O band, in the spectrum of the BiOCl/MIL-100(Fe) hybrid was blueshied compared with that in the spectrum of BiOCl, which indicates that BiOCl and MIL-100(Fe) were coupled. 1,43 The morphologies of the hybrids were investigated via SEM, as shown in Fig. 2.…”

“…Besides the above-mentioned catalysts, to increase the efficiency of light utilization, many visible-light-induced catalysts have been developed. Tang et al found that the degradation efficiency of carbamazepine could be attained to 85% by BiOBr/MIL-53(Fe) with visible light exposure (Tang et al 2019). The doping of in BiOBr photocatalyst can improve the separation efficiency of photogenerated carriers.…”

Bi4O5Br2 with irregular flake shape was synthesized by a facile and energy-saving hydrolysis method. Its band gap energy (Eg) was 2.1 eV. The formation mechanism was proposed. The Bi4O5Br2 exhibited superb visible-light-induced photocatalytic activity (>90%) toward the oxidation of carbamazepine. The kinetics rate constant (k) attained 0.0196 min−1. The effect of Bi4O5Br2 dosage, initial solution pH value, and inorganic anions on carbamazepine degradation was investigated. During the oxidation process, photogenerated holes (h+) and superoxide radical anions (•O2−) were the main active species. Based on the reaction intermediates results determined through a combined system of liquid chromatography and mass spectrometry, a possible reaction mechanism was speculated. The degree of contamination of carbamazepine solution after treatment was evaluated through the teratogenic effect experiment. After 120 min of visible light exposure, the carbamazepine solution is free of pollution. Also, the as-synthesized Bi4O5Br2 maintains good chemical stability and could be reused in photodegradation process, indicating its potential in practical applications.
