Enhanced decoloration activity by Cu2O@TiO2 nanobelts heterostructures via a strong adsorption-weak photodegradation process

- Cu2O@TiO2 nanobelts were synthesized with wet chemical precipitation method. Heterostructures were formed between Cu2O particles and TiO2 nanobelts.
- A strong adsorption-weak photodegradation process was proposed.
- The strong adsorption is attributed to the exposure of the {1 1 1} facets of Cu2O.
