What is it about?
Investigation of the effects of Zr-doping in silver niobate (AgNbO3) had been carried out to improve the photocatalytic performance of AgNbO3. The X-ray diffraction patterns of the AgNbO3 and Zr-doped AgNbO3 showed that the materials are pure and have no overall change in phase upon Zr-doping. The photocatalytic performance of Zr-doped AgNbO3 was also studied for the degradation of RhB and MB dyes under visible light.

Why is it important?
The Fourier transform infrared spectra showed an intense wide band due to bonding between Nb and O which is observed within the specified range of AgNbO3. Field emission scanning electron microscopy analysis showed that the particle size decreases with increasing Zr-doping. Tauc plots derived from the UV–Vis absorption spectra showed that Zr-doping has a limited effect on band gap narrowing. Furthermore, the photoluminescence data was indicative of lowered charge recombination rate in the Zr-doped AgNbO3 compared to AgNbO3. The photocatalytic performance of Zr-doped AgNbO3 was also studied for the degradation of RhB and MB dyes under visible light.
