The n–p homojunction design in semiconductors could enable directed charge transfer, which is promising but rarely reported. Herein, TiO2 with a spatial n–p homojunction has been designed by decorating TiO2 nanosheets with Ti vacancies around nanostructured TiO2 with O vacancies. 2D 1H TQ-SQ MAS NMR...
