Environmentally Benign Organic Dye Conversion under UV Light through TiO<sub>2</sub>-ZnO Nanocomposite
In this work, we developed a very simple and novel approach for synthesizing TiO<sub>2</sub>-ZnO nanocomposites via the urea-assisted thermal decomposition of titanium oxysulphate and zinc acetate at different weight ratios. The synthesized nanocomposite samples were studied by means of...

In this work, we developed a very simple and novel approach for synthesizing TiO<sub>2</sub>-ZnO nanocomposites via the urea-assisted thermal decomposition of titanium oxysulphate and zinc acetate at different weight ratios. The synthesized nanocomposite samples were studied by means of HR-TEM, XRD, STEM, UV–Vis DRS, PL and EDS. The observed results demonstrate that the TiO<sub>2</sub>-ZnO nanocomposite consists of an anatase crystal phase of TiO<sub>2</sub> with a crystallite size of 10–15 nm. Combined characterization, including UV–Vis DRS, STEM, EDS and HR-TEM, revealed the successful formation of a heterojunction between TiO<sub>2</sub> and ZnO and an improvement in UV spectrum absorption. The photocatalytic activity was explored using MO degradation under ultraviolet light illumination. The results of the optimized TiO<sub>2</sub>-ZnO nanocomposite show excellent photocatalytic activity and photostability over a number of degradation reaction cycles. In addition, the current approach has immense potential to be used as a proficient method for synthesizing mixed metal oxide nanocomposites. |
