| Abstract: | Muscovite was used to prepare muscovite/nano-TiO2 compsosite photocatalyst due to the difficulty application of the nano-TiO2 powder. The photocatalyst was used to treat wastewater containing azo dye. The results show that the decoloration effect of the photocatalyst on the wastewater reached more than 61% and that azo dye contained in the wastewater was photodegraded. The compsite photocatalyst can be used in wastewater treatment and environment-friendly coatings, etc. |
