Photocatalytic selective oxidation of phenol in suspensions of titanium dioxide with exposed {0Â 0Â 1} facets

- Facet-induced selective oxidation was studied based on high-energy TiO2 nanocrystals.
- Catechol and hydroquinone are main intermediates in selective oxidation of phenol.
- Both exposed facets and surface fluorination affect selectivity (yield) of catechol.
