Self-assembly of bioinspired catecholic cyclodextrin TiO2 heterosupramolecule with high adsorption capacity and efficient visible-light photoactivity

- Two kinds of PCA-β-CD modified TiO2 nanomaterials were easily obtained through a facile supramolecular dip coating.
- The high surface coverage of TiO2 by the attached PCA-β-CD with the controlled orientation.
- PCA-β-CD/TiO2 heterosupramolecules showed a promising adsorption capacity as well as a high and reusable visible-light photoactivity to bisphenol A.
- We reported a facile and comprehensive suparmolecular assembly strategy of introducing cyclodextrin onto metal oxide.
