Soft chemically synthesized zinc oxide micro-flowers for the enhanced photocatalytic properties and their analytical determination

The zinc acetate di-hydrate and sodium hydroxide were used in synthesis of zinc oxide micro-flowers (ZnO-MFs) via soft chemical process and photocatalytic activity determined in presence of methylene red (MR) dye. The crystallinity and morphology of the grown nanostructures were investigated using XRD, FESEM, and TEM. Additionally, the analytical method was also applied to observe the concentration of ZnO-MFs affected on organic methylene red dye, which was established by statistical parameters. The absorption spectra of ZnO-MFs composed with nanorods and MR dye show maximum absorbance at 540 nm. The optical and regression characteristics of the proposed method were evaluated by analytical techniques. (C) 2014 The Korean Society of Industrial and Engineering Chemistry.
