Essential properties such as particle size, solution stability, structural morphology and photocatalytic efficiency of the resulting TiO2-PPy were all assessed in order to gain an understanding on the relationship between the structure, properties, and catalytic performance.

The chemistry and bioavailability of trace elements in different plants and sources is diverse [11].
Copper is the 3rd largest element and it is part of the structure of antioxidant enzymes such as super oxide dismutase.
