In this work, ZnO nanocrystals (NCs) have been effectively synthesized by a simple, efficient and cost-effective method using coconut husk extract as a novel fuel.The synthesized NCs are characterized by UV-Vis, Shower Door Hardware XRD, FT-IR, SEM, EDX, Raman and PL studies.The obtained ZnO were found to be UV-active with a bandgap of 2.

93 eV.The X-ray diffraction pattern confirms the crystallinity of the ZnO with hexagonally structured ZnO with a crystallite size of TEA TREE PLUS 48 nm, while the SEM analysis reveals the hexagonal bipyramid morphology.Photocatalytic activities of the synthesized ZnO NCs are used to degrade methylene blue and metanil yellow dyes.
