•Unusual features of oxygen plasma activation for Au/TiO2 photocatalysts are reported.
•The oxygen plasma activated sample exhibits the highest visible-light activity.
•A feature of oxygen plasma activation is high content of surface oxygen.
•Another feature is of benefit to forming low-coordinated Au around the interface.
