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...
