- •
Cu NPs introduce the SPR and result in an increase of visible light absorption.
- •
The photocatalytic activity of Cu2O/Cu improves greatly due to the SPR effect.
- •
A dark catalytic activity is observed stemming from the Fenton-like reaction.
- •
The •O2− and •OH radicals contribute to the photocatalytic process.
- •
The •OH radicals contribute to the dark catalytic process.
