“…[43] Moreover, the XRD of melem-heteropolyacid also showed the main reflections at the 2θ of about 28, 32, and 34 due to (121), (123), and (121), which fits well with that of melem. [31] Typical and strong diffraction peaks were observed for H 5 PW 10 V 2 O 40 in Figure 6b that confirmed generation of crystalline state for this heteropolyacid, as can be seen in the XRD pattern of CuO-melem- heteropolyacid (Figure 6c). Particle size of CuO-melemheteropolyacid was estimated using the Scherer equation (Equation 1):…”

The in situ photocatalytic oxidation of aromatic alcohols to aldehydes by air under visible-light-driven condition is an attractive and beneficial route regarding environmental crises and worldwide energy economy. Herein, CuOmelem-heteropolyacid nanophotosensitizer is disclosed as an efficient heterostructured nanocomposite involving H 5-n PW 10 V 2 O 40 nÀ … (melem-NH 3 + ) n ionic liquid, successfully prepared via a facile and straightforward procedure.This nanocomposite is characterized employing routine techniques such as Xray diffraction (XRD), Fourier transform infrared (FT-IR), diffuse reflectance spectra (DRS), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), field emission scanning electron microscopy (FE-SEM),and Brunauer-Emmett-Teller (BET). The resultant nanocomposite exhibited superior photocatalytic efficacy than its pristine melem, HPA, and CuO constituents in the in situ photo-oxidation of benzylic alcohols and in the fast condensation with o-phenylenediamine to generate a range of 2-substituted benzimidazoles, as important precursors in the synthesis of important pharmaceuticals under the illumination of a green laser light (λ 535 nm). This study suggests a radical pathway involving reactive species such as •O 2 À and OH• together with h + in a photocatalytic process. Stability and reusability experiments along with hot filtration test ensured sufficient reproducibility of the nanophotocatalyst in the reaction medium. At the final part of this study, the in vitro cellular cytotoxicity of CuO-melem-heteropolyacid nanohybrid material was evaluated on A549 human lung cancer cell line with the MTT assay.The distinct reduction in cell viability affirmed cytotoxicity of the nanomaterial against the performed cell line.

The present study reports an environmentally safe synthesis of CuO NPs employing Echinophora platyloba DC extract. The production of CuO NPs was authenticated using various analytical characterization techniques such as FT-IR, TEM, XRD, SEM-EDX, DLS, zeta potential, and UV-Vis. The DPPH assay was employed to assess the scavenging efficacy of synthesized CuO NPs. The results of the MTT assay exhibited that CuO NPs have efficient anticancer potential on two used cancer cell lines (MCF-7 and Burkitt's lymphoma). Thus, it tempts us to study the synthesized CuO NPs biocompatible aspects by interactions with several biologically significant molecules. The present experimental evidence demonstrates the direct interaction of CuO NPs with DNA, which might be one of the credible highways elevating its anticancer potential. Moreover, we investigated the interaction of CuO NPs with the most important blood proteins (HSA, HHb, and Lys) in simulated physiological conditions using spectroscopic methods. The interaction findings suggest that the native conformation of the above proteins was preserved at the level of secondary structure in spite of complex formations with CuO NPs. The binding constant values revealed the greater binding affinity of CuO NPs with HSA, HHb, and Lys as compared to ct-DNA; the binding affinity was found in the order HSA > HHb > Lys > ct-DNA.

“…Subsequently, an organic pollutant is decomposed directly via a photogenerated hole or indirectly through a reaction with distinct reactive groups such as the hydroxyl radical, superoxide radical anion, and hydroperoxyl radical. [7][8][9][10][11][12] The characteristic reactive groups are very reactive species owing to their unique redox potential, which oxidizes nearly all organic contaminants to their mineral products. It has been reported that the photocatalytic activity of photocatalysts depends on several features, such as surface morphology, crystallinity, particle size, shape and surface defects.…”

“…In the photocatalytic degradation mechanism, an electron‐hole pair occurs when the ZnO is activated with photons equal to or greater than the band gap energy (Eg) of the photocatalyst. Subsequently, an organic pollutant is decomposed directly via a photogenerated hole or indirectly through a reaction with distinct reactive groups such as the hydroxyl radical, superoxide radical anion, and hydroperoxyl radical [7–12] . The characteristic reactive groups are very reactive species owing to their unique redox potential, which oxidizes nearly all organic contaminants to their mineral products.…”

Photocatalysis is the most environmentally benign and efficient method for degrading organic dyes in water purification. Herein, the synthesis of ZnO nanoparticles was achieved by simple homogeneous chemical precipitation via the support of adipic acid and followed the calcination process at elevated temperatures. Based on the physical and morphological characterization analysis, the high crystallinity hexagonal structure with uniform granular shape morphology of the ZnO nanoparticles was formed with a band gap of 3.2 eV. The photocatalytic performance of the ZnO nanoparticles was investigated with the degradation of methylene blue (M.B.) dye as a model compound in an aqueous medium under UV light irradiation. The optimal ZnO‐700 nanoparticles demonstrated the highest photocatalytic activity thanks to their large surface area and numerous oxygen vacancies. More importantly, a small amount of photocatalyst (0.4 g/L) successfully degraded M.B. dye from an aqueous solution with 100 % efficiency within just 11 minutes of irradiation time under UV light with protective photocatalytic activity 4 sequential cycles. Besides, in‐depth photocatalysis experiments present that via a facile two‐step synthesis method, the as‐prepared ZnO photocatalysts depict enhanced chemical stability in a harsh environment and efficient photodegradation.
