Oxygen Vacancies Assisted Photocatalytic Dye Degradation and Photoelectrochemical Water Splitting Performance in Ag and Mg-modified NaNbO3

A lead-free Na0.85Ag0.15Nb0.95Mg0.05O3 (AM-NN) polycrystalline ceramic was synthesized using the conventional solid-state reaction method, and its structural, dielectric, impedance, and optical properties were thoroughly investigated. X-ray diffraction (XRD) and Rietveld...
