“…Nanoscale materials including oxide materials and compounds have been examined by scholars because of their unique nanostructures and extraordinary attributes. [34][35][36][37] These compounds are technologically a very beneficial kind of material because of their usage in environmental remediation. [38][39][40] For the NH 3 -SCR reaction, catalysts such as single metal oxides, mixed metal oxides and supported metal oxides, and pure or metal-exchanged zeolites have consistently demonstrated superior de-NO x performance and N 2 selectivity under oxygen-rich conditions, preventing the formation of secondary pollution in the NH 3 -SCR.…”

“…The MB is a dye type that oxidized in the presence of hydroxyl radical and decomposes into CO 2 and H 2 O. According to the Beer-ambert law, the MB concentration affects the methylene blue absorbance, so the destruction of methylene blue structure leads to a decrease in its absorption intensity [1,42,43]. Hydroxyl radical was detected using methylene blue as a free radical sensor.…”

Eu doped zinc sulfide quantum dots (QDs) were prepared by the chemical Co-precipitation method. X-ray diffraction analysis (XRD), scanning electron microscopy (SEM) and infrared Fourier transform (FT-IR) analysis were used to characterize the quantum dots. The size of nano-crystals was estimated using a Williamson Hall equation.Then, the synthesized nanoparticles were studied to investigate the antibacterial effect, containing different strains of pathogenic bacteria, and the lowest inhibitory concentration and halo diameter were calculated. WilliamsonHall equation of about 6 nm with a strain of 0.7 nm, which is match with the reported size of the SEM image.The photoluminescence spectrum (PL) of ZnS:Eu QD in excitation wavelength of 280 nm shows two emission peaks at 384 and 715 nm. In order to use these QDs as photosensitizer in photodynamic therapy, anthracene and methylene blue chemical detectors were used for detection of singlet oxygen and hydroxyl radical, respectively.The significant point for these quantum dots is that, in addition to production of hydroxyl radical, they also have the ability to produce singlet oxygen with UVC radiation. The antimicrobial effect of ZnS:Eu QDs was also investigated using a disc diffusion method on 11 microbial strains. The results of this test showed that Two microorganisms S.dysenteriae, Serotype that were resistant to the antibiotic nystatin and showed the highest sensitivity to ZnS:Eu QDs.

Nanobiotechnology is a unique class of multiphase and recently become a branch of contemporary science and a paradigm shift in material research. One of the two main problems facing the field of nanomaterial synthesis is the discovery of new natural resources for the biological production of metal nanoparticles and the absence of knowledge about the chemical composition of bio-source required for synthesis and the chemical process or mechanism behind the production of metal nanoparticles presents the second difficulty. We reported template-free green synthesized copper oxide nanoparticles using Tribulus terrestris seed natural extract without any isolation process. XRD, TEM, SEM, UV–Vis, DLS, zeta potential, and BET evaluated the synthesized metal nanoparticle. The TEM analysis confirmed that the CuO NPs are well dispersed and almost round in shape with an average size of 58 nm. EDAX confirms that copper is the prominent metal present in the nanomaterial. The greener fabricated copper oxide nanoparticle was employed to degrade methyl orange dye, almost 84% of methyl orange was degraded within 120 min. The outcomes demonstrated the nanomaterial’s effective breakdown of contaminants, highlighting their potential for environmental rehabilitation. The electrochemical investigation of the CuO NPs was utilized for supercapacitor application. An appreciable value of specific capacitance is 369 F/g specific capacitances with 96.4% capacitance retention after 6000 cycles. Overall, the results of the current study show that the biologically produced copper oxide nanoparticles have intriguing uses as photocatalysts for treating water contaminants and are suitable for energy storage devices.
