研究目的
To evaluate the photocatalytic efficiency of nano MgFe-doped TiO2 under visible light according to the composition ratio of Mg, Fe and TiO2.
研究成果
Nano MgFe–TiO2 photocatalyst showed high removal efficiency under visible light due to the doping of N-type semiconductors like Mg and Fe into TiO2, which prevents electron and hole recombination and improves hole transporting function.
研究不足
The study focuses on the photocatalytic efficiency under specific conditions (visible light irradiation) and does not explore the full range of potential applications or environmental conditions.
