Influence of Synthesis Conditions on The Photocatalytic Activity of Polypyrrole/Zinc Oxide Composites

An interaction of conductive polymer and metal oxide particles may contribute to achievement of specific properties and enhanced photocatalytic activity of obtained material. This work studies the development of composite structures based on polypyrrole/zinc oxide (PPy/ZnO) with increased photocatalytic performance under solar radiation due to components‘ synergistic activity in such composite material. It is very important to optimize the synthesis conditions in order to obtain composite material PPy/ZnO with high surface area, the optimal thickness of conductive polymer layer on ZnO and also minimal possible aggregation of metal oxide particles. In this study several composites of PPy/ZnO were prepared. The duration of synthesis was from 30 to 90 min. Obtained composite samples were characterized by Fourier transform infrared spectroscopy (FTIR), UV-Vis spectroscopy, thermogravimetric analysis (TGA) and scanning electron microscopy (SEM). The decomposition of dye Reactive Red 45 (RR 45) under UV and solar light was used to estimate the photocatalytic efficiency of prepared composite samples. The obtained results show that duration of synthesis highly influences the photocatalytic efficiency of composites.
