The presence of composite in the nanofluid is essential for significant removal of methylene blue in industrial waste water. Silver oxide nanoparticles on zinc oxide nanoparticles showed increased photocatalytic activity. The study successfully synthesized ZnO/Ag2O nanoparticles by utilizing flower extract as a reducing and stabilizing agent. The nanoparticles exhibited high photocatalytic activity and small particle size.
The presence of composite in the nanofluid resultant is essential to provide a significant methylene blue (MB) removal property in industrial waste water. Silver oxide (Ag2O) nanoparticles (NPs) placed over zinc oxide (ZnO) NPs had a significant increase in photocatalytic activity. The Ag2O NPs doped ZnO NPs were synthesised in the current study by utilising Millingtonia hortensis flower extract and a simple green synthesis procedure. The floral extract is a fantastic reducing and stabilizing agent. ZnO has been doped along with Ag2O Nanofluid (NF) (volumes of ZnO 10 ml, 15 ml, 20 ml, and 25 ml). The crystalline nature of the produced material was investigated using powder XRD analysis. To confirm the presence of silver in nanofluids, the EDAX spectrum and UV-Vis spectral analysis were employed. The EDAX spectrum established the materials' compositions, while the FESEM analysis revealed the various surface morphologies of the generated materials. ZnO/Ag2O (NPs) catalysts degraded the organic dye MB. ZnO/Ag2O NPs (25 ml Ag2O NF) degrade at a rate of 63 percent after 120 min of irradiation, due to their large surface area. The typical particle size of synthesised nanoparticles is 16-17 nm. The photocatalytic activities are enhanced when particles from the flower are extracted, according to the characterization data.
