“…Zhan et al reported the similar results [64] . In addition, the reason that the MB removal rate was still higher under alkaline conditions may be due to the fact that the cationic dye MB has more adsorption per unit volume, generating a large number of reactive sites compared with the anion dye MO, which enhances the degradation rate in natural light [27] . Interestingly, the results of Chaúque et al showed that in a weakly acidic media (pH = 5), the quantitative transfer of hydrogen ions from MO molecule to nanocomposites was higher, and decreased either as the concentration of hydrogen ions increased or in a neutral to alkaline medium [67] .…”

“…The photocatalytic activities of different nanofibrous membranes were investigated in terms of the degradation of the cationic dye MB and the anionic dye MO using 10–100 mg/L aqueous dye solution [22] , [27] . For each sample, 20 mg nanofibrous membrane was immersed in MB or MO solution (10 mg/L, 100 mL).…”

“…Semiconductor photocatalyst has been used widely for the treatment of the water as compared to another conventional photocatalyst. [10][11] ZnO is having a wide bandgap with large excitation binding energy, which found for a large number of applications (UV laser, dye-sensitized solar cells, and gas sensing) by a virtue of its wide bandgap energy. The photocatalytic activity of ZnO gets restricted due to the expeditious rate of electron-hole recombination and lack of sunlight absorption.…”

The present study deals with the synthesis of ZnO and Ag‐ZnO nanoparticles using Excoecaria agallocha leaf extract under a controlled ultrasound cavitation technique. The characterization of the as‐synthesized ZnO and Ag‐ZnO nanoparticles (different molar concentration of Ag) were subjected to Fourier transform infrared spectroscopy (FTIR), X‐ray diffraction analysis (XRD), UV‐Visible Diffuse reflectance spectroscopy (UV‐Vis DRS), Thermogravimetric analysis (TGA), N2 adsorption‐desorption isotherm (BET), scanning electron microscopy(SEM) and transmission electron microscopy (TEM). The photocatalytic performance of ZnO and Ag‐ZnO nanoparticles as catalysts were studied for hazardous organic dyes such as methylene blue (MB) and rhodamine‐B (Rh−B) under solar light irradiation. The degradation study follows pseudo‐first‐order kinetics. The effective degradation of MB was found to be 56.44 % (ZnO nanoparticles) and 98.44 % Ag‐ZnO nanoparticles, respectively at 100 min at the molar ratio (0.25 : 1). Whereas, Rh−B shows 27.50 % (ZnO nanoparticles) and 98.83 % at the same molar ratio of Ag‐ZnO nanoparticles at 80 min. Among the as‐synthesized nanoparticles, Ag‐ZnO at molar ratio 0.25 : 1 shows effective photocatalytic activity. Besides these as‐synthesized nanoparticles exhibited good antimicrobial activity with an increase in Ag nanoparticles decorated into ZnO. A similar trend was observed in antioxidant and anti‐inflammatory activity.

Solar light induced organic pollutant degradation is an ideal approach for wastewater treatment and environmental challenges. The as-synthesized nanofibers (NFs) exhibited significant photocatalytic activity towards both the dyes (anionic and cationic) under solar light irradiation. Present work reports, preparation of AgÀ G nanoparticles (NPs) impregnated in PAN NFs using electrospinning technique. The recyclability of AgÀ G NPs impregnated PAN NFs becomes very easier due to formation PAN NFs mat with impregnation of highly porous structure of AgÀ G NPs as compared to powder catalyst. The as-prepared PAN/AgÀ G NFs were subjected for structural, optical and morphological study. Under solar light irradiation, PAN/ AgÀ G NFs shows excellent photocatalytic performance of methylene blue (MB) (88.19%, 75mins) and methyl orange (MO) dyes (82.5%, 90 min) degradation respectively. TOC values and rate constants of the samples indicate the superior catalytic efficiency as compared to AgÀ G NPs and PAN NFs. Under solar radiation, mechanism and plausible pathway of photocatalytic dye degradation is also reported.
