10.3.2 OPTIMIZATION STUDY

In the present work, the involved factors such as CuO content in the preparation of

TiO

2

/CuO nanocomposite and pH of dye solution during photocatalytic degradation

were investigated, and the respective response in terms of % degradation of MB was

carefully studied. As mentioned in the previous sections, 0.5 g TiO

/CuO powder

with varied CuO content i.e. 0.06–0.30 g was added into a 250 ml of 50 mg/l dye

solution and maintained at different pH in the range of 4–9 based on the design ...
