“…Meanwhile, due to the simple operation of reducing Ag from silver compounds, many groups have designed a series of Ag/Ag m X n /Bi 2 MoO 6 composites with the aims of both generating more charge carriers and further separating the e − –h + pairs. For instance, Lv et al constructed a Ag/Ag 2 WO 4 /Bi 2 MoO 6 composites via in situ photoreduction of Ag 2 WO 4 ; Yan et al deoxidized Ag + ions in AgCl/Bi 2 MoO 6 using UV–vis light irradiation …”

Highly active photocatalysts driving chemical reactions are of paramount importance toward renewable energy substitutes and environmental protection. As a fascinating Aurivillius phase material, Bi 2 MoO 6 has been the hotspot in photocatalytic applications due to its visible light absorption, nontoxicity, low cost, and high chemical durability. However, pure Bi 2 MoO 6 suffers from low efficiency in separating photogenerated carriers, small surface area, and poor quantum yield, resulting in low photocatalytic activity. Various strategies, such as morphology control, doping/defect-introduction, metal deposition, semiconductor combination, and surface modification with conjugative π structures, have been systematically explored to improve the photocatalytic activity of Bi 2 MoO 6 . To accelerate further developments of Bi 2 MoO 6 in the field of photocatalysis, this comprehensive Review endeavors to summarize recent research progress for the construction of highly efficient Bi 2 MoO 6 -based photocatalysts. Furthermore, benefiting from the enhanced photo catalytic activity of Bi 2 MoO 6 -based materials, various photocatalytic applications including water splitting, pollutant removal, and disinfection of bacteria, were introduced and critically reviewed. Finally, the current challenges and prospects of Bi 2 MoO 6 are pointed out. This comprehensive Review is expected to consolidate the existing fundamental theories of photo catalysis and pave a novel avenue to rationally design highly efficient Bi 2 MoO 6 -based photocatalysts for environmental pollution control and green energy development.

“…Bismuth- or ferrum-based semiconductor oxides generally possess a moderate bandgap energy (~ 2.0 eV) and are regarded as an important class of visible-light-responsive photocatalysts [9–19]. Among them, BiFeO 3 with a perovskite-type structure is found to exhibit interesting photocatalytic performance for the dye degradation and water splitting under visible-light irradiation [20–25].…”

In this work, Ag3PO4 microparticles were decorated onto the surface of BiFeO3 microcuboids through a precipitation method to obtain p-Ag3PO4/n-BiFeO3 heterojunction composites. The composites were employed for the degradation of acid orange 7 (AO7) under visible-light irradiation. It is found that the composites exhibit much higher photocatalytic efficiency than bare BiFeO3. Meanwhile, the intrinsical visible-light-driven photocatalytic activity of Ag3PO4/BiFeO3 composites was further confirmed by the degradation of phenol. In addition, the photo-Fenton-like catalysis property of the composite was also evaluated. The photocurrent analysis indicates that the combination of BiFeO3 with Ag3PO4 leads to the inhibition of recombination of photoinduced electrons and holes. The obvious enhancement in the photocatalytic activity of the composite is mainly ascribed to the efficient photogenerated charge separation and interfacial charge migration caused by the formation of Ag3PO4/BiFeO3 p-n heterojunctions.

“…Among these photocatalysts, Ag 2 WO 4 presents good photocatalytic performance for dye degradation under light irradiation [30–31 36–37]. Unfortunately, due to its wide bandgap of about 3.1 eV, Ag 2 WO 4 has limited photocatalytic activity under sunlight, which severely limits its application and illustrates the urgency for optimization of Ag 2 WO 4 to overcome these disadvantages [38–42]. …”

“…As a consequence, some Ag 2 WO 4 -based composites containing VLD components such as Ag 2 S/Ag 2 WO 4 [40], C 3 N 4 /Ag 2 WO 4 [39], Bi 2 MoO 6 /Ag 2 WO 4 /Ag [42] etc., have been reported to show improved VLD performance in the degradation of pollutants. To the best of our knowledge, application of AgI/Ag 2 WO 4 as a VLD photocatalyst for the degradation of toxic pollutants remains unreported.…”

To develop efficient and stable visible-light-driven (VLD) photocatalysts for pollutant degradation, we synthesized novel heterojunction photocatalysts comprised of AgI nanoparticle-decorated Ag2WO4 nanorods via a facile method. Various characterization techniques, including XRD, SEM, TEM, EDX, and UV–vis DRS were used to investigate the morphology and optical properties of the as-prepared AgI/Ag2WO4 catalyst. With AgI acting as the cocatalyst, the resulting AgI/Ag2WO4 heterostructure shows excellent performance in degrading toxic, stable pollutants such as rhodamine B (RhB), methyl orange (MO) and para-chlorophenol (4-CP). The high performance is attributed to the enhanced visible-light absorption properties and the promoted separation efficiency of charge carriers through the formation of the heterojunction between AgI and Ag2WO4. Additionally, AgI/Ag2WO4 exhibits durable stability. The active species trapping experiment reveals that active species (O2 •− and h+) dominantly contribute to RhB degradation. The AgI/Ag2WO4 heterojunction photocatalyst characterized in this work holds great potential for remedying environmental issues due to its simple preparation method and excellent photocatalytic performance.
