“…The photocatalytic mechanism to degrade the organic pollutant could indicate as below (Scheme 1) [38][39][40] : 09 would be used by the sacrificing reagent. Accordingly, the photoinduced carriers are spatially separated with the internal electric field assistance is created at the interface, which highly hinders the recombination of photoinduced electrons and holes.…”

Recently, water pollution caused by dyes and organic pollutants (such as methyl orange and methylene blue) has been produced through industrial textiles, leather, pharmacy, etc., which has become a serious ecological issue. [1][2][3] Consequently, several technologies, such as chemical precipitation, adsorption, and membrane, have been applied to treat these toxic organic contaminants from water. 4-6 Among these used methods, photocatalysis has attracted extensive attention due to the unique advantages such as low energy consumption, easy fabrication, repeatable process, high removal efficiency, and limited chemical requirement. 7 In the photocatalysis process, sunlight is used as a source of energy; the process begins with absorbing a photon and continues by generating electrons and holes. The electron and holes pairs react with oxygen, water, and produce active radicals, which could destroy organic pollution in water. 8,9 That is

“…There are many methods to remove artificial dyes from drinking water such as nanofiltration [1] , adsorbent [2] , biosorption [3] and the photocatalytic process [4] , [5] . Among them, the photocatalytic activity received more attention because of its privileges of low energy consumption, high stability, environmental and economical friendly [6] , [7] , [8] , [9] . The mechanism of photocatalytic process is described in the following path: (1) the absorption of photons with energy ≥ the bandgap of nano-photocatalyst, (2) photoexcited electrons create at conduction band and the same amount of positive holes at valence band, (3) The various oxidants of OH • , O 2 • and H 2 O 2 could proficiently oxidize dye compounds into harmless combinations of CO 2 and water [10] , [11] , [12] .…”

In recent decades, antimicrobial resistance of different bacteria against various antibiotics and contamination of water resources by various dyes has been one of the most important human problems. Therefore, in this research, biogenic silver nanoparticles were synthesized using nontoxic and rapid approach using Pistacia khinjuk leaves extract (P. khinjuk) as compatible and safe reducing agent (PKL@AgNPs). Nanoparticle optimization experiments were performed at different times, temperatures and concentrations in order to achieve the most optimal conditions. The biosynthesized AgNPs were characterized in terms crystalline, morphology and structural. The Fourier-transform infrared spectroscopy (FT-IR) spectra showed that the phenol compounds present in the P. khinjuk leaves extract were responsible for silver ion (Ag + ) reduction and stabilization of AgNPs (Ag 0 ). X-ray powder diffraction (XRD), field emission scanning electron microscopy (FESEM), and transmission electron microscopy (TEM) analysis results revealed that the product were facecentered cubic structure, homogeneous, uniformly, oval-like and spherical morphology with size of about 35-45 nm. The biosynthesized AgNPs exhibited a high photocatalytic activity for the degradation of the methylene blue (MB) and methyl orange (MO) as hazardous contaminants. The degradation efficiency of PKL@AgNPs for MB and MO pollutants were 93.2% and 85.37% under UV and 75.18% and 70.03% under sun-light irradiations, respectively. Furthermore, the PKL@AgNPs showed strong antibacterial and antifungal activities against Escherichia coli, Klebsiella pneumoniae, Staphylococcus aureus, Streptococcus mutans, Streptococcus mitis, Enterococcus faecalis, and Candida albicans with minimum inhibitory concentration (MIC) values of 0.58, 0.58, 0.58, 1.17, 2.34, 1.17, and 0.15 μg ml À1 , respectively. The antioxidant activity of PKL@AgNPs was calculated and the results revealed that the percentage of DPPH inhibition increased (3.8% to 69.9%) with increasing the concentration of nanoparticles. Also, the PKL@AgNPs also revealed significant
