Dependence of photocatalytic activity on structural and optical properties of nanocrystalline ZnO powders
Source abstract
Abstract
Abstract Nanocrystalline ZnO powders were prepared from cetyltrimethylammonium bromide (CTAB)-modified NaOH, NH 4 OH and (CH 2 ) 6 N 4 solutions. The calcined ZnO powders exhibited a hexagonal structure without any secondary phase. Different shapes of ZnO powders were formed depending on CTAB concentration and type of precipitating agent. As (CH 2 ) 6 N 4 solution was used, rod-like ZnO structure was changed to a spherical shape when CTAB concentration was increased. The widest E g value of approximately 3.23 eV was obtained from the sample containing the lowest defect concentration. The decolorization efficiency was higher than 90% after irradiating for 90 min and the sample with higher E g value showed higher decolorization efficiency.
