“…A new element, Cl, was observed in the Bi 2 O 3 after photodegradation at a pH value of 3.0, as shown in Figure 9a(3). Highresolution XPS (HR-XPS) analysis of Bi4f in the pre-and post-photocatalytic degradation Bi 2 O 3 samples (Figure 9b) showed that two feature peaks of the binding energies of 159.1 and 164.5 eV corresponded to Bi 4f 7/2 and Bi 4f 5/2 of the trivalent bismuth ion (Bi 3+ ), respectively [78,79]. Figure 9c displays the HR-XPS analysis of the post-degradation Bi 2 O 3 microrods, from which we can see that the two highest-intensity peaks located at around 199.8 and 198.2 eV corresponded to Cl 2p 1/2 and Cl 2p 3/2 in the region of Cl 2p, respectively, which demonstrated that BiOCl was easily produced on the surface of Bi 2 O 3 after degradation in the acidic environment [80].…”

In the present work, the photodegradation of Rhodamine B with different pH values by using Bi2O3 microrods under visible-light irradiation was studied in terms of the dye degradation efficiency, active species, degradation mechanism, and degradation pathway. X-ray diffractometry, polarized optical microscopy, scanning electron microscopy, fluorescence spectrophotometry, diffuse reflectance spectra, Brunauer–Emmett–Teller, X-ray photoelectron spectroscopy, Fourier-transform infrared spectroscopy, UV–visible spectrophotometry, total organic carbon, and liquid chromatography–mass spectroscopy analysis techniques were used to analyze the crystal structure, morphology, surface structures, band gap values, catalytic performance, and mechanistic pathway. The photoluminescence spectra and diffuse reflectance spectrum (the band gap values of the Bi2O3 microrods are 2.79 eV) reveals that the absorption spectrum extended to the visible region, which resulted in a high separation and low recombination rate of electron–hole pairs. The photodegradation results of Bi2O3 clearly indicated that Rhodamine B dye had removal efficiencies of about 97.2%, 90.6%, and 50.2% within 120 min at the pH values of 3.0, 5.0, and 7.0, respectively. In addition, the mineralization of RhB was evaluated by measuring the effect of Bi2O3 on chemical oxygen demand and total organic carbon at the pH value of 3.0. At the same time, quenching experiments were carried out to understand the core reaction species involved in the photodegradation of Rhodamine B solution at different pH values. The results of X-ray photoelectron spectroscopy, Fourier-transform infrared spectroscopy, and X-ray diffractometer analysis of pre- and post-Bi2O3 degradation showed that BiOCl was formed on the surface of Bi2O3, and a BiOCl/Bi2O3 heterojunction was formed after acid photocatalytic degradation. Furthermore, the catalytic degradation of active substances and the possible mechanism of the photocatalytic degradation of Rhodamine B over Bi2O3 at different pH values were analyzed based on the results of X-ray diffractometry, radical capture, Fourier-transform infrared spectroscopy, total organic carbon analysis, and X-ray photoelectron spectroscopy. The degradation intermediates of Rhodamine B with the Bi2O3 photocatalyst in visible light were also identified with the assistance of liquid chromatography–mass spectroscopy.

“…SPR-induced photocatalysis technology utilizes the unique properties of plasma metals to remarkably improve the efficiency of photocatalytic reactions under low-intensity illumination conditions. [94][95][96] Typically, the plasma metal oscillates resonantly with incident photons in the appropriate wavelength range, leading to the generation of a local electromagnetic field, which then decays non-radiometrically to produce significant amounts of hot electrons that participate in the subsequent photocatalytic reaction. [97] In Bi/semiconductor photocatalysts, both the photoabsorption capacity and the efficiency of photogenerated carrier separation are enhanced by incorporating surface self-deposited Bi metal.…”

“…These experimental results suggested that the photothermal conversion efficiency of Bi/Bi 4 O 5 Br 2 materials gradually improved with the increase of metallic Bi content, and the SPR effect of Bi was the main factor affecting the photothermal conversion.

Semiconductor photocatalysis has great potential in the fields of solar fuel production and environmental remediation. Nevertheless, the photocatalytic efficiency still constrains its practical production applications. The development of new semiconductor materials is essential to enhance the solar energy conversion efficiency of photocatalytic systems. Recently, the research on enhancing the photocatalytic performance of semiconductors by introducing bismuth (Bi) has attracted widespread attention. In this review, we briefly overview the main synthesis methods of Bi/semiconductor photocatalysts and summarize the control of the micromorphology of Bi in Bi/semiconductors and the key role of Bi in the catalytic system. In addition, the promising applications of Bi/semiconductors in photocatalysis, such as pollutant degradation, sterilization, water separation, CO2 reduction, and N2 fixation, are outlined. Finally, an outlook on the challenges and future research directions of Bi/semiconductor photocatalysts is given. We aim to offer guidance for the rational design and synthesis of high‐efficiency Bi/semiconductor photocatalysts for energy and environmental applications.

BiOCl is a promising photocatalyst, but due to its weak visible light absorption capacity and low photogenerated electron−hole pair separation rate, its practical application is limited to a certain extent. In this study, a novel double Z-scheme heterojunction UiO-66-NH 2 /BiOCl/Bi 2 S 3 catalyst was constructed to broaden the visible light response range and promote high photogenerated hole−electron separation of BiOCl. Its photocatalytic performance is evaluated by dissociating tetracycline (TC) and rhodamine B (RhB) in visible light. The optimal proportion of UiO-66-NH 2 /BiOCl/Bi 2 S 3 hybrids exhibits the best degradation efficiency of visible light illumination (∼93% in 120 min for TC and ∼98% in 60 min for RhB). The synergistic effect of a large visible light response range and the Z-scheme charge transfer mechanism ensure the excellent visible photocatalytic activity of UiO-66-NH 2 /BiOCl/Bi 2 S 3 . It is proven that h + and •O 2 − are the main active substances in the photocatalysis process by active substance capture experiments and electron spin resonance tests. The intermediates and degradation processes are analyzed by high-performance liquid chromatography−mass spectrometry. This study proves that the new UiO-66-NH 2 /BiOCl/Bi 2 S 3 photocatalyst has great application potential in the field of water pollution degradation and will provide a new idea for the optimization of BiOCl.
