Zea mays L. dry husk extract was used to bio synthesize copper oxide nanoparticles. Red coloured cubic Cu 2 O nanoparticles were obtained for the first time via this simple, eco-friendly, green synthesis route. The Cu 2 O nanoparticles were thermally oxidized to pure monoclinic CuO nanoparticles at 600 °C. The phases of the copper oxides were confirmed from the x-ray diffraction (XRD) studies. The nanoparticle sizes as obtained from high resolution transmission electron microscope (HRTEM) analysis range from 10 to 26 nm, 36-73 nm and 30−90 nm for the unannealed Cu 2 O, 300 °C and 600 °C annealed CuO respectively. The values of the bandgap energies obtained from diffuse reflectance of the nanoparticles are 2.0, 1.30 and 1.42 eV respectively for the unannealed, 300 °C, and 600 °C annealed copper oxide nanoparticles. The 600 °C annealed copper oxide nanoparticles showed 91% and 90% degradation ability for methylene blue dye (BM) and textile effluent (TE) respectively under visible light irradiation. While CuO_300 is more effective to inhibit the growth of Escherichia coli 518,133 and Staphylococcus aureus 9144, Cu 2 O is better for Pseudomonas aeruginosa and Bacillus licheniformis. The results confirm the photo-catalytic and anti-microbial effectiveness of the copper oxide nanoparticles.

“…The presence of peaks at 1078.21 cm −1 and 871.82 cm −1 , attributed to C-O stretching vibrations, typical in alcohols, ethers, and esters, further supports the presence of ascorbic acid. Finally, the peaks observed at 823.60 cm −1 , 727.16 cm −1 , 630.72 cm −1 , 547.78 cm −1 , and 459.06 cm −1 are likely associated with metal-oxygen (Cu=O) in the Cu2O/AA NPs [44].…”

This study addresses the critical need for efficient and recyclable photocatalysts for water treatment applications by presenting a novel approach for the synthesis and characterization of copper (I) oxide (Cu2O) nanoparticles modified with ascorbic acid (Cu2O/AA). The motivation for this research stems from the increasing concern about environmental pollution caused by organic pollutants, such as Brilliant Cresyl Blue (BCB), and the necessity for sustainable solutions to mitigate this issue. Through comprehensive characterization techniques including Ultraviolet–Visible spectroscopy (UV-Vis), Fourier Transform Infrared spectroscopy (FTIR), X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), zeta potential measurements, and Brunauer–Emmett–Teller (BET) analysis, we demonstrate a significant modification to the electronic structure, enhancing the photocatalytic activity of Cu2O/AA. BET analysis revealed a mesoporous structure with a specific surface area of 2.7247 m2/g for Cu2O/AA, further emphasizing its potential for enhanced catalytic performance. The photocatalytic degradation studies showcased remarkable efficiency improvements, with degradation coefficients of 30.8% and 73.12% for Cu2O NPs and Cu2O/AA NC, respectively, within a 120 min timeframe. Additionally, recyclability experiments indicated sustained efficiency over five consecutive cycles, with both catalysts retaining crystalline integrity. These findings underscore the promising potential of Cu2O/AA nanoparticles as highly efficient and recyclable photocatalysts for the degradation of organic pollutants, offering superior performance compared to pure Cu2O NPs and addressing the pressing need for sustainable water treatment solutions.

Nanomaterials are now widely used in a variety of fields, such as biomedicine and industry, and the world is experiencing its worst conditions yet as a result of the spread of bacteria and the rise in the number of people infected with various diseases as a result of coming into contact with nanomaterials. The spread of pollution can be curtailed by the use of new techniques and experiments. Microorganism membranes can be penetrated by nanoparticles, making nanostructured materials a necessity in biological research. The plasma jet technology is powerful enough to sterilize and kill the bacteria in a small space. There are a wide variety of industrially essential coatings that Magnetron sputtering can be applied to, including those used in the medical industry. We'll go over the history, foundation, and several uses of this method in this review. Other recent discoveries, such as the creation of copper oxide nanoparticles in each of the two processes, are also covered. It can be used in a variety of fields, including biomedical applications.
