Heterogeneous photocatalysts have been used for the degradation of organic compounds/dyes to carbon dioxide, water and mineral ions and refreshed the environment. Perovskite materials are well known in this field because of their narrower band gap (＞3.0 eV) which can be easily excited under visible light or UV light irradiation. In this work, we described the synthesis of single phase, nanoparticles Bi3TiNbO9 by simple co-precipitation method under basic condition (pH~ 9). The formation of prepared perovskites materials were confirmed by XRD patterns (JCPDS 7-192). The photocatalytic activity for degrading methylene blue over Bi3TiNbO9 under UV-illumination is comparatively well with respect to reported one. The rate of photodegradation of methylene blue was evaluated by using UV-Vis spectrophotometer. Co-precipitation is one of the simplest wet-chemical techniques to synthesize advanced ceramic powders with narrow particle size distribution. The synthesized materials were characterized by XRD, FT-IR, SEM, BET surface area, and UV-Vis spectrophotometer. |
