Abstract
Using different amount of potato peels, ZnO photocatalysts (ZO-PC) have been prepared by facile combustion process followed by the calcination at 500 degrees C for 10 min, and their obtained nanomaterials have been investigated through various techniques like powder X-ray diffraction (XRD), scanning electron microscope (SEM) combined with EDX, transmission electron microscope (TEM), Fourier transform infrared spectroscopy (FTIR), and UV-Vis spectroscopy in DRS mode. Moreover, the spectrophotometry technique has been employed to investigate the degradation of methylene blue (MB) under UV irradiation light (lambda < 400 nm) by fabricated ZO-PCs. Among them, the lowest peel-containing sample was exhibited enhanced photocatalytic activity as compared to others also optical bandgap energy (E-g) was increased with increasing of peels from 3.39 to 3.49 eV.
