a Schematic illustration for the formation of surface oxygen vacancies on Bi3TiNbO9. Blue, gold and purple spheres represent Ti/Nb, Bi and O atoms, respectively. b Crystal structure of Bi3TiNbO9. TEM image of (c) BNT-P, SAED pattern (inset) and (d) atomic-resolution ABF-STEM image of BNT-OVP. Inset: magnified view of (d) with corresponding Bi (cyan) and Ti/Nb (blue) columns. HRTEM images of (e) BNT and (f) BNT-OVP. g EPR spectra of BNT, BNT-P, BNT-OV2 and BNT-OVP.
