摘要：
ZnO nanopowder was synthesized by hydrothermal method and characterized by different spectroscopic techniques. X-ray diffraction measurements reveal the hexagonal wurtzite stnicture of ZnO and the average crystallite size is evaluated as 34 nm. Morphological and chemical compositional details were investigated by SENT TEM and EDS analysis. Optical absorption spectrum exhibited a characteristic exciton absorption hand at 363 nm. PI, spectrum exhibited various hands in UV and visible regions. FT-IR. spectrum exhibited the characteristic ZnO and other functional groups. Visible light driven photocatalytic degradation of methylene blue (MB) dye in water was used to evaluate the photocatalytic performance of the prepared ZnO nanopowder.
