Beschreibung
Zusammenfassung:	[Display omitted] •N-doped BaTiO3 photocatalyst was synthesized by urea addition solid state synthesis.•N-doped BaTiO3 shows improved photocatalytic activity irradiated by visible light.•Nitrogen dopant and oxygen vacancy are the main factors that enhance the activities. Regular nitrogen-doped BaTiO3 particles were synthesized by urea addition solid state sintering method. Compared with the undoped samples, the N-doped photocatalyst shows improved activities of photodegradation to Rhodamine-B under visible light irradiation (420nm
