氢化的{001}面占主导地位的TiO 2纳米片在其表面上具有O-H键和O−。高活性的{001}晶面通过Ti-H键的形成得以保持。氢化反应产生大量的Ti 3+离子和氧空位，改善了光吸收，提高了光催化活性。
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.
