“…Trench and colleagues 44 synthesized novel heterojunctions consisting of α-Ag 2 WO 4 /Ag 3 PO 4 with different α-Ag 2 WO 4 contents and AgNPs on the surface via coprecipitation route to utilize for organic pollutant degradation such as RhB. For this purpose, AgNO 3 was used as a source of Ag, then by using (NH 4 ) 2 HPO 4 and (NH 4 ) 2 HPO 4 as precursors in different bakers at room temperature, α-Ag 2 WO 4 and Ag 3 PO 4 were synthesized.…”

Plasmonic nanoparticles are able to enhance the photocatalytic performance of semiconductor nanoparticles using four main mechanisms of light scattering, light concentration, hot electron injections, and plasmon-induced resonance energy transfer. Pushing the semiconductor nanoparticles' absorption range to the visible and near-infrared and boosting the electron−hole generation quantum yield are the major effects. However, most of the reviewed papers lack a systematic design for conjugation of plasmonic nanoparticles with semiconductor nanoparticles, and they mainly benefited from the general enhancement because of the generated localized surface plasmon resonances. In this Review, we have systematically showed the importance of rational optical design of plasmonic-semiconductor nanoparticle conjugation for an efficient photocatalytic activity. The application of plasmon-enhanced phenomenon for the environmental remediation and green energy production was thoroughly reviewed. The degradation of organic dyes, air pollutants, volatile organic compounds, pesticides, and pharmaceutical compounds were the major reviewed works in environmental applications, while the green energy productions were limited to the role of plasmonic nanoparticles for the enhancement of H 2 /O 2 production, water splitting, and CO 2 reduction. This review can be a useful guideline for researchers working on enhancing the photocatalytic activity of the semiconductor nanoparticles and those interested in plasmon-enhanced phenomena by emphasizing the underlying mechanisms.

“…Hence, it is necessary to tune this characteristic to enhance efficiency in diverse applications, and the oxide/Ag 2 WO 4 composite has been used for this purpose. Composite systems with simple oxides such as Ag/ (ZnO, [205], MnWO 4 /Ag 2 WO 4 [206], Ag 2 WO 4 /CeO 2 [207], a-Ag 2 WO 4 /Ag 3 PO 4 [208], CoOeAg 2 WO 4 [209,210], ZnBi 2 O 4 /Ag 2 WO 4 ) [211], and Ag 2 WO 4 /(TiO 2 ,ZnO)/AgX (X ¼ Cl, Br, I) [187e189] have been obtained for diverse synthetic routes. These last three heterojunctions have been described in the present work in the section on composites with Ag 2 WO 4 crystals and halogenbased materials.…”
