Synthesis of zinc oxide nanoparticles (ZnO NPs) with banana peels extract (BPE) from jackfruit banana: effect of pH and reaction time: article

This present study is about synthesis ZnO NPs with Banana Peels Extract (BPE) from Jackfruit Banana by varying pH and reaction time. This method on producing ZnO NPs by using eco-friendly method especially biological method which are less harmful and BPE is choose as reducing agent and act as stabilizer. The samples were then characterized to identify the optimum condition found at pH 12 and 60 mins . The results Fourier Transform Infra Red (FTIR) Spectroscopy shown ZnO bonds allocate at range of 500-571 cm-1for all sample, while for UV-Visible (UV-Vis) the band gap energy was found in between 3.34eV and 3.43eV. Furthermore, by using the X-ray Diffraction (XRD) determine the crystalline size within the range of 12.11nm to 16. 32 nm for pH. The average crystallite size at pH 12 was 14.16 nm while at 60 min was 14.16nm smallest particle size for reaction time. Brunaner-Emmet-Teller (BET) analysis shown all the samples were nanoparticles because less than 100 nm size of particle. Lastly, for Zeta- Potential analysis, the sample size is larger than 100nm because sample were highly agglomerates.
