Green synthesis of ZnO NPs using aqueous extract of Epipremnum aureum leave: Photocatalytic degradation of Congo red

The present perspective describes green synthesis of ZnO nanoparticles (NPs), a prominent semiconductor having high band gap (3.73 eV), from an aqueous extract of Epipremnum aureum leave. Several spectroscopic and analytical techniques, including UV–Vis, FT-IR, XRD, SEM, EDX, and TGA confirmed the bio-synthesis of ZnO NPs. The XRD analysis ratified the hexagonal crystalline structure of ZnO NPs with a tiny size found as 19.31 nm. An approximately similar size (29 nm) was noticed from an SEM study with a great extent of thermal stability up to 160 °C. Apart from these, UV–Vis, and FT-IR spectra confirmed the initial formation of NPs and functional groups derived from plant leaves associated with NPs. The prominent application of this study was to appraise…
