Synthesis, characterization, and morphological control of PbWO4 nanostructures through precipitation method and its photocatalyst application

In current study, we synthesized PbWO4 using co-precipitation method. Also the effect of three capping agents, polyethylene glycol, cetyltrimethylammonium and sodium dodecyl sulfate on the size of particles, morphology, and photocatalystic properties of nano-structures was investigated. The techniques we employed to characterize the morphological, optical, magnetic and structural properties of as-obtained products were, scanning electron microscopy, vibrating sample magnetometer, energy dispersive X-ray, UV-Vis spectroscopy and X-ray diffraction. The methyl orange method was utilized to assess photocatalytic activity of as-obtained nano-particles under ultraviolet (UV) radiation. Our findings validated that PbWO4 can be decolorized up to maximum value of 97% under 90 min UV irradiation.
