文摘

Lead molybdate (PbMoO₄) nanostructures, has been successfully prepared via a simple precipitation method. In this method, lead acetate trihydrate and ammonium heptamolybdate tetrahydrate were applied as starting reagents to fabricate PbMoO₄ nanostructures. The effect of different capping agents like valine, alanine, and glycine on the morphology and particle size of the products has been investigated. The as-synthesized nanostructures were characterized by X-ray diffraction, scanning electron microscopy, diffuse reflectance spectroscopy (UV–Vis), and energy dispersive X-ray microanalysis (EDX). According to the vibrating sample magnetometer, lead molybdate (PbMoO₄) nanostructures indicated a ferromagnetic behavior at room temperature. To evaluate the catalytic properties of nanocrystalline lead molybdate, the photocatalytic degradations of methyl orange under ultraviolet light irradiation were carried out.
