“…TiO 2 or ZnO) composite photocatalysts have been extensively studied as in the removal of pollutants. [22][23][24][25][26][27][28][29][30] These heterogeneous photocatalysts require high energy in the ultraviolet region to overcome a large band gap or complex synthetic route to increase their stability. 21 In addition, such metal-based photocatalysts can contaminate the water treatment process, depending on their retrieval and separation method as well as corrode in an aqueous environment.…”

“…Argentous oxide (Ag 2 O) belongs to a visible-light-driven photocatalyst with a narrow band gap (1.2 eV) [12][13][14]. However, the application of Ag 2 O is limited owing to the high cost and instability for the decomposition into metallic Ag during the photocatalytic degradation of the inorganic pollutants [15]. Nanocomposites formed from semiconductors and Ag 2 O can work as efficient and stable visible-light photocatalysts [16,17].…”

A photo-deposition method was developed to synthesise argentous oxide/calcium aluminate nanocomposites (Ag2O-CAONCS) with orthorhombic Ca5Al6O14 and cubic Ag2O phases. Micro-morphology, micro-structure, optical, and visible-light catalytic properties were investigated via different techniques. Ag2O enhances visible-light absorption performance and decreases the band gap of the Ag2O-CAONCS. About 20 mL crystal violet (CV) dye (10 mgL–1) is totally degraded using 20 mg Ag2O-CAONCS under sunlight irradiation for 20 min. The enhanced photocatalytic activity of the Ag2O-CAONCS towards CV under sunlight irradiation is ascribed to the reduction of the band gap, improvement in visible-light absorption and inhibitation role of carriers recombination by Ag2O. The high, stable visible-light catalytic activity makes Ag2O-CAONCS promising photocatalysts for removing organic pollutants.

“…ZnO NPs and metal ion doped ZnO's photocatalytic activity were evaluated by measuring how well MB dye degraded under UV illumination (De, A. K., Majumdar, S et al, (2020), (Tijani, J. O et al, (2019). Additionally, ZnO NPs perform as bioactive compounds with a range of applications, such as antioxidant and antibacterial properties (Shaukat, N et al, (2021), (Shen et al, (2020). Uncertainty exists about Ag-doped Zno NPs' photocatalytic activity and biocompatibility.…”

Zinc oxide (ZnO) has a variety of characteristics, including optical, electrical, mechanical, thermal, and structural. Nanoparticles (NPs)play a big part in many different industries. The current research focuses on producing ZnO Nps for photocatalytic dye degradation activities. Ag2O-doped ZnO was produced together with three other different types of ZnO NPs. Nps as well as pure ZnO nanocrystals, were recovered using chemical and biological methods. The SEM study supported the chemical evolution of the ZnO nanorod-like structure, which exhibits enhanced photocatalytic activity. It was predicted that chemically produced ZnO Nps would have 34 nm, the typical particle size. X-ray diffraction analysis was used to identify Ag2O/ZnO nanoparticles in their hexagonal configuration. The particle size ranged from 16 to 17 nm, which was shown to be the norm. The findings of the SEM study further demonstrate that the created Ag2O doped ZnO Nps agglomerated into hexagonal forms, stuck together as bulks and rods, and grew in size in proportion to the Ag nanofluids. We conclude that hexagonal and rod-shaped Ag2O/ZnO Nps aggregates work well as photocatalytic catalysts. Approximately 25 mL of ZnO-doped Ag2O nanofluid is a powerful photocatalyst for oxidizing organic dyes and is suitable for large-scale applications
