Synthesis and Characterization of Lead Molybdate Nanostructures with High Photocatalytic Activity Via Simple Co-precipitation Method

In this study, lead molybdate (PbMoO4) nanostructures were synthesized successfully via a simple and fast co-precipitation method. A new lead precursor [pb(2-hydroxyacetophenone)]2 was used for synthesis of the product. It was seen that using lead complex led to create of very tiny structures that can be attributed its steric effect. Different parameters such as pH, surfactant kind and solvent were changed to study their effect on the product size and morphology. It was found each parameter can effect on the product shape and change particle size and morphology. Different analysis such as scanning electron microscopy, X-ray diffraction pattern, Fourier transform infrared spectroscopy and energy-dispersive X-ray spectroscopy were used to characterize the fabricated products. Also photocatalytic activity of the product was studied by UV–Visble spectroscopy and it was found that synthesized lead molybdate can act as photocatalyst under visible light range.
