文摘
- •
ZnO nanomaterials were successfully prepared by three different methods.
- •
Different preparation method, fuels and different molar ratio of citric acid fuel modified optical properties of ZnO.
- •
The catalytic activity of ZnO nanomaterials was evaluated using dye method for decomposition of Remazol Red RB 133.
- •
The highest photocatalytic activity is found in a gel precursor containing citric acid in the molar ratio of 1.
