文摘
- •
Long wavelength visible light to UV and short wavelength upconversion by Er3+:Al2O3.
- •
Higher photoactivity of rutile due to extra short-wavelength visible light adsorption.
- •
Er3+:Al2O3/TiO2-SAC possessed high photocatalytic capability under visible light.
- •
RSM model is significant and predicts well for the actual experimental values.
- •
Photocatalytic degradation followed the Langmiur–Hinshelwood kinetics.
