Abstract

In this paper, strontium molybdate (SrMoO4) nanostructures were synthesized via a sonochemical method based on the reaction between strontium (II) nitrate and ammonium heptamolybdate tetrahydrate in water. Capping agents are frequently used in colloidal synthesis to inhibit nanoparticle overgrowth and aggregation as well as to control the structural characteristics of the resulted nanoparticles in a precise manner; therefore, glucose and lactose were applied as capping agents. Besides, the effect of glucose and lactose on the morphology and size of final products were investigated by SEM analysis. According to the vibrating sample magnetometer, SrMoO4 nanostructures indicated a ferromagnetic behavior at room temperature. To evaluate the catalytic properties of nanocrystalline SrMoO4, the photocatalytic degradations of methyl orange under ultraviolet light irradiation were carried out. The structural, morphological, magnetic, and optical properties of as-obtained products were characterized by techniques such as XRD, SEM, EDX, VSM, and UV–Vis spectroscopy.
