“…Based on the results it may be concluded that the oxidative degradation of dye in presence of AgNPs by K 2 S 2 O 8 is radical ion based mechanism and the main radical ion species generated during the catalytic activation of K 2 S 2 O 8 was sulphate radical ions (SO 4 •− ). The role of the catalyst as a mediator for the electron transfer to PDS was also reported [ 32 , 48 , 49 ].…”

The present study includes the Azadirachta indica (neem) induced Silver nanoparticles (AgNPs) by green synthesis as reducing and capping agent. Synthesized AgNPs were characterized by different instrumental techniques such as XRD (X-ray Diffraction), SEM (Scanning Electron Microscopy), TEM (Transmission Electron Microscopy), Zetasizer, UV-Visible and FT-IR (Fourier Transformation Infra-Red) spectroscopy. The result of XRD reveals that nanoparticles were crystalline in nature and pure, stability was determined by Zeta potential and SEM, TEM analysis indicates that AgNPs was monodisperse in a spherical shape with average size 9 nm. These synthesized AgNPs were applied as the catalyst in the degradation process of Methyl Orange (MO) and wastewater samples in presence of peroxodisulphate (PDS). Effect of different experimental conditions such as initial pH, concentration of PDS, Dye, and AgNPs was studied on the degradation process. The obtained kinetic result shows that AgNPs/PDS system induces 1.1 × 10−4 to 15.9 × 10−4 s-1 folds in presence of the small concentration of AgNPs (1 × 10−8 mol dm−3). The degradation of MO and real wastewater samples in AgNPs/PDS system is followed pseudo-first order kinetics and maximum degradation of MO reached 88% in 40 min and real wastewater samples in 80 min. Liquid chromatography-mass spectrometry (LC-MS) analysis and UV-Visible spectral changes were used to analyze the structure of intermediate and end products (CO2, H2O, NO3−, and O3S−) during the degradation process. Furthermore, the result of biodegradability index (greater than 0.3) implies that advanced oxidation process enhances the biodegradability of wastewater.

“…These methods have significant disadvantages such as incomplete color removal, production of harmful side products, efficacy only in low concentration, expense and high energy requirement. Of late, practically sound advanced oxidation processes (AOPs) came into existence which include Fenton 18 19 , photo-Fenton 20 , ozonization 21 , TiO 2 photocatalysis 22 23 , photolysis using H 2 O 2 24 25 and O 3 26 etc. One of the highly promising and cost effective AOPs is the use of TiO 2 (anatase), a semiconductor catalyst under UV radiation for the mineralization of organic pollutants 27 .…”

Controlled shape and size with tuneable band gap (1.92–2.41 eV), nickel sulphide NPs was achieved in presence of thiourea or thioacetamide as sulphur sources with the variations of temperature and capping agents. Synthesized NPs were fully characterized by powder XRD, IR, UV-vis, DRS, FE-SEM, TEM, EDX, XPS, TGA and BET. Capping agent, temperature and sulphur sources have significant role in controlling the band gaps, morphology and surface area of NPs. The catalytic activities of NPs were tested for round the clock (light and dark) decomposition of crystal violet (CV), rhodamine B (RhB), methylene blue (MB), nile blue (NB) and eriochrome black T (EBT). Agitation speed, temperature, pH and ionic strength have significant role on its catalytic activities. The catalyst was found to generate reactive oxygen species (ROS) both in presence and absence of light which is responsible for the decomposition of dyes into small fractions, identified with ESI-mass spectra.

“…61,62 Moreover, pH of solution is a main factor which inuences dye degradation as pH affects the surface charge properties of the catalyst. 63 Hence, to optimize reaction pH for AB-10B dye degradation, the considered range of pH was 3.0 to 9.0 as illustrated in Fig. 7A.…”
