Abstract:
Defective perovskite SrTiO3 has been synthesized by rapid solidification of its melts obtained from arc-melting treatment. As a result of rich and stable defects implanted in SrTiO3, the bandgap was narrowed from 3.29 eV to 3.08 eV. Correspondingly, the defective SrTiO3 powders exhibit highly enhanced photocatalytic performance.
