“…[15][16][17][18] In particular, Bi 3 O 4 Cl has a layered Sillén-Aurivillius-related oxide structure consisting of [Bi 3 O 4 ] layers sandwiched between two slabs of [Cl] ions in an extraordinarily open crystalline structure. 19,20 On account of the distinctive crystalline structure, there is a self-built internal static electric eld to facilitate the separation and transportation of photogenerated electrons and holes to improve the photocatalytic performance. 21 However, unfortunately, the use of Bi 3 O 4 Cl is constrained by its weak visible light absorption and low rate of charge transfer when applied in practice.…”

“…The strong inhibition of the degradation efficiency in presence of EDTA‐2Na and partial suppression by the addition of BQ can be found, and thus it can be concluded that the hole and •

play key roles during the photocatalysis in the presence of Ag 4 V 2 O 7 /g‐C 3 N 4 and Ag 4 V 2 O 7 /Ag 2 VO 2 PO 4 /g‐C 3 N 4 heterojunctions. ESR spin‐trap with DMPO is a useful technique employed to monitor reactive oxygen species generated in the reaction system . The ESR spectra of the reaction solutions using AVP/CN ‐ 0.05 and 0.15 as catalysts are shown in Figure .…”

A novel Ag 4 V 2 O 7 /g-C 3 N 4 heterostructure was synthesized by a facial etching method in ammonia solution using Ag 2 VO 2 PO 4 /g-C 3 N 4 as a self-sacrifice precursor. With the concentration of ammonia solution increasing from 0.05 to 0.2 M, phase transformation took place, described as: exhibited dramatically improved activity for the degradation of methylene blue (MB), methyl orange (MO) and imidacloprid under visible light irradiation. When etched with 0.15 M ammonia solution, an Ag 4 V 2 O 7 /g-C 3 N 4 heterostructure was obtained that exhibited the highest photoactivity. This photocatalyst was nearly 9.1, 3.0, and 24.3 times more efficient than pristine Ag 2 VO 2 PO 4 /g-C 3 N 4 for degradation of MB, MO and imidacloprid, respectively.The excellent photocatalytic performance can be ascribed to the as-obtained welldefined Ag 4 V 2 O 7 /g-C 3 N 4 heterojunction, which improves the separation and transfer efficiency and prolongs the lifetime of photoinduced charges. In addition, the stability and dominant radicals were investigated.

“…To further investigate the essence of active oxygen species in BiOCl and BiOCl/RhB system under visible light irradiation, electron spin resonance (ESR) spin‐trap technique was employed to identify the superoxide (•O 2 − ) in methanol‐medium and hydroxyl radicals (•OH) in water‐medium with 0.1 mg mL −1 sample containing 50 mM DMPO . As shown in Figure b, the strong signals of the superoxide radical species are found over RhB/BiOCl in methanol‐medium, whereas no signals are observed in BiOCl system, suggesting the incapability of BiOCl for generating free radicals under visible light irradiation. Meantime, signals of •OH are hardly detected over BiOCl or RhB/BiOCl in water‐medium with and without visible light irradiation (Figure c).…”

Hierarchical BiOCl microspheres assembled from nanosheets with predominated (110) facets were facilely fabricated by precipitation at room temperature and characterized systematically. The effects of the solvents, chlorine precursors and reaction time on the growth of the BiOCl microspheres have been investigated in detail. Rhodamine B (RhB) was selected to evaluate the photocatalytic activity of the as‐obtained samples under visible‐light irradiation, and the results revealed that the BiOCl microspheres synthesized with WCl6 exhibited superior RhB removal efficiency through a photosensitization process, and the degradation efficiency was 99% within 25 min and was still kept over 97% after five runs. The enhanced photocatalytic activities were mainly attributed to their hierarchical structure, high specific surface area as well as more exposed (110) facet. The superoxide radicals (•O2−) were demonstrated to be the main active species in the photodegradation process. Additionally, photocatalysis mechanism was proposed based on experimental results.
