Solar water splitting with nanostructured hematite: the role of oxygen vacancy

Surface defect engineering has shown to be an effective way to prepare cheap and efficient photoanode. In this study, oxygen vacancies are introduced to the hematite photoanode by a stepped atmosphere calcination with varied duration. The property of oxygen vacancies is verified by XRD, TEM, XPS and...
