In recent years, the nanotechnology has gained much attention since the nanoparticles (NPs) have applications in every field of life. The hetero-structured are of special interest due to their higher photocatalytic activity. In present investigation, Zinc vanadate NPs were synthesized from vanadium and zinc salts by microwave assisted precipitation method. The Zinc vanadate NPs were characterized by x-ray Powder Diffraction (XRD), Energy-dispersive x-ray spectroscopy (EDX), Scanning electron microscope (SEM) and UV-visible techniques. The photocatalytic activity (PCA) was evaluated by degrading the methylene blue (MB) dye and process variables were optimized. The Zinc vanadate size was <100 nm and particles were in aggregates form. The MB dye degradation was performed at different conditions of process variables and it was observed that MB dye was significantly degraded using Zinc vanadate NPs under UV light irradiation. The reaction time, catalyst dose and dye initial concentration showed variable effect on dye degradation. Based on results, it can be concluded that the microwave irradiation is viable for the synthesis of Zinc vanadate NPs for photocatalytic activity. In view of promising efficiency of Zinc vanadate NPs, it can be used for the dye degradation and for the remediation of textile effluents.

Nanoparticles (NPs) are among the several NMs that can function as nano carriers because of their improved solubility, prolonged release, targeting potential, and aid in medication dosage reduction. Recent developments are discussed in this overview. To distribute medications, these small materials can locate the precise location in the body. In addition, they can lessen the negative effects of medications and assist patients in taking fewer pills while still achieving the same or better benefits. The development of nanoparticle medication delivery systems has been one of the most important research fields. This brief overview will concentrate on the traits that make for effective drug delivery systems based on nanoparticles as well as the numerous disease conditions where these nanoparticle systems have shown promise.
