Abstract
Dye pollution became a serious environmental and health challenge in many industrialized cities of the world. Natural dye degradation process takes a long time and thus, dye wastewater requires treatment before release into the environment. Zinc oxide (ZnO) nanoparticles were readily synthesized for photocatalytic dye degradation using phytochemicals from the leaves of Dieffenbachia seguine Linn. The phytochemicals present in the aqueous leaf extract of dumb cane or Dieffenbachia seguine (L) were used as reducing and stabilizing agents for the synthesis of ZnO nanoparticles (ZnONPs). The ZnONPs shows effective capping and stabilization by the phytochemicals as observed by the Fourier-Transform Infrared Spectroscopy. The particle size of the synthesized ZnONPs was studied using transmission electron microscopy. In this study, we used phytosynthesized ZnONPs for the degradation of Methylene Blue under UV Light. The ZnONPs photocatalyst showed excellent activity with over 95% of the dye degraded within 30 minutes. This highlights the strong potential of the ZnONPs as photocatalyst for the treatment of dye wastewater.
