Abstract
ZnO nanopowder with crystallite size in the range 55-97 nm was prepared by combustion technique and was
characterized by powder X-ray diffraction, scanning electron microscope, and Fourier transform infrared
spectroscopy. Photocatalytic degradation of acid orange 8 (AO8) dye was carried out with ZnO nanopowder. The
effect of amount of ZnO, concentration of the dye, pH and irradiation time on photocatalytic degradation of AO8
is studied. The results reveal that the maximum decolorization (more than 70%) of dye occurred with ZnO catalyst
in 35 min of stirring at alkaline pH.
