Abstract The large tree species Terminalia catappa is a member of the Combretaceae family and mainly found in tropical climates. They are commonly cultivated for shade because they have huge, dense foliage. Numerous polyphenols, including flavonoids, tannins, saponins, phytosterols, present leaves. In this study, green chemical method was used to extract polyphenols from dried almond were employed synthesis Cu 2 O nanoparticles as reducing agent. FTIR UV–Vis describe leaf after chlorophyll removed. Copper salt create via reduction process. extract's potential photocatalytic dye degradation has also been explored. obtained had spherical shape with dimensions 50–100 nm, its band gap energy reached 1.945 eV remove methylene blue aqueous media under visible light irradiation conditions. At an initial MB concentration 10 ppm, decomposition efficiency 71.99% only h exposure simulated sunlight. process occurred according pseudo-first-order kinetic model rate constant 0.0084 min −1 .

Abstract Synthesis of nano‐particles using various greener approaches such as the use plant extract, microbes, etc. is gaining a lot popularity in scientific community due to their advantages being cheaper protocol, reduction less hazardous chemicals, more environmentally benign method and good yield. It has been previously reported by many research groups that material provides reducing, capping well stabilizing agents brings down biological environmental risks green synthesis nano‐particles. So it was thought worthwhile synthesize copper oxide (CuO NPs) some locally available medicinal plants. Rivina humilis L. plants which are our region Vidarbha Maharashtra State, India considered be herbal for treatment respiratory‐related disorders mainly asthma cold local tribal peoples. found contains variety phytochemicals can employed nanomaterials. With this aim present an efficient approach (RH) whole extract. For characterization bio‐synthesized CuO NPs, spectral analytical techniques UV‐Vis spectroscopy, FT‐IR, XRD, SEM, TEM, EDS were employed. The newly synthesized NPs also tested potential activities against six different bacterial stains namely E. coli , P. aeruginosa S. aureus vulgaris B. subtilis typhi diffusion method. antioxidant efficacy undertaken through 1,1‐Diphenyl‐2‐picrylhydrazyl (DPPH) free radical scavenging activity. Their results have presented discussed work.
