Abstract

Hydrogenated {001}-facets-dominated anatase TiO₂ nanosheets have O–H bonds and O⁻ on their surface. The high reactive {001} facets were maintained by the formation of Ti–H bonds. A large number of Ti³⁺ ions and oxygen vacancies were produced by hydrogenation, resulting in improved light absorption and enhanced photocatalytic activity.
