Industrial effluents containing various dyes are a potential threat to the environment and its remediation has become a challenging task for the scientists. We demonstrated here for the first time the ultrafast and improve dye degradation capability of bismuth ferrite (BFO) nanoparticles by molybdenum doping prepared through a facile chemical route. Phase purity and microstructural characterization of the prepared samples were carried out using thermogravimetric analysis (TGA), X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), UV-vis and photoluminescence (PL) spectroscopy. It was observed that doping of molybdenum not only enhance the photocatalytic activity by four-fold of the pristine sample but also make the process very fast. Experimental results delineate that 10 mg/l rhodamine-B (RhB) degrades more than 80% under irradiation of visible light for only 5 min at the ambient condition without using any remarkable promoter. Also, it can also degrade other dyes (methylene blue, bismark brown) and the process is almost independent of pH which is good for application purpose. In totality, molybdenum doped BFO nanoparticles could be very good promising candidates for dye degradation to clean industrial effluents quickly through an easy and inexpensive way for the benefit of society.

Keywords: Dye-degradation, Mo-doped BFO, Nanoparticles, Rhodamine B, Ultrafast, Visible light.
