ZnO NPs were synthesized in three different pine bark extract ratios, which acts as a reducing and stabilizing agent. The produced ZnO NPs were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectrum analysis (EDS) and ultraviolet-visible light spectroscopy (UV-VIS).It was determined that the XRD diffraction peaks were consistent with the characteristic peaks of ZnO, and ZnO NPs were produced in the hexagonal wurtzite crystal phase. It was determined from the SEM images that the samples were produced homogeneously which have almost spherical geometry and the average particles were in the range of 20-30 nm. In the elemental analysis, only Zn and O elements were observed without any impurity atoms. Also, the degradation performance of methylene blue (MB) dye under UV light was determined to determine the photocatalytic activities of ZnO NPs. It was determined that MB reached almost 66% degradation efficiency after 80 minutes of UV illumination of ZnO NPs synthesized by using pine bark extract.}, number={1}, publisher={Adana Alparslan Türkeş Bilim ve Teknoloji Üniversitesi}
