New nanocomposites containing zirconium were synthesized using microwave irradiation. Their structure was confirmed by vibrating sample magnetometer (VSM) curves, X-ray diffraction (XRD) patterns, scanning electron microscope (SEM) and transmission electron microscopy (TEM) images, Fourier transform infrared spectroscopy (FT-IR), and Brunauer–Emmett–Teller (BET) N2 adsorption/desorption isotherms. After the structure confirmation of the zirconium magnetic nanocomposite, the catalytic properties in the synthesis of pyrazole derivatives were investigated. Next, the biological activities of the zirconium magnetic nanocomposite, such as the antibacterial and antifungal activities, were investigated. The research results showed that the zirconium magnetic nanocomposite has high catalytic properties and can be used as a magnetic nanocatalyst for synthesizing heterocyclic compounds such as pyrazole derivatives in addition to having high biological properties. The unique properties of the nanoparticles can be attributed to their synthesis method and microwave radiation. [ABSTRACT FROM AUTHOR]

The novel Ag0/Cu 2 MoO 4 nanoparticles was simply synthesized via chemical method. Ag/Cu 2 MoO 4 nanoparticles was characterized by FESEM image, XRD curve, UV–vis spectroscopy, BET analysis, and XPS spectrum. XRD pattern depicts that the cubic crystalline phase of particles. The band gap of Ag/Cu 2 MoO 4 nanoparticles was achieved to 2.04 eV, which that depicted the best activity under visible light irradiation. Ag/Cu 2 MoO 4 nanoparticles exhibits 99.74% degradation under light and persulfate ion which was higher response than Cu 2 MoO 4 nanoparticles (83.56%) under this condition. The scavenging test indicates the important reactive species in removal process were •OH, and •SO 4 −. The Ag/Cu 2 MoO 4 nanoparticles was indicated highly photo-stability for the MG degradation after 5th cycle. Ag/Cu 2 MoO 4 exhibits substantial antibacterial properties against P. aeruginosa and S. pneumoniae. Moreover, Ag/Cu 2 MoO 4 nanoparticles was experimented to peroxidase-like performance for the colorimetric detection of glucose with the Limit of Detection about 52.23 nM. • Ag/Cu 2 MoO 4 nanoparticles synthesized by facile chemical method. • Ag/Cu 2 MoO 4 nanoparticles proficiently activate persulfate ions resulting in enhanced photocatalytic dye degradation. • Ag/Cu 2 MoO 4 nanoparticles exhibit the highest bactericidal activity. • The peroxidase like activity of Ag/Cu 2 MoO 4 nanoparticles was tested to detection glucose detection.
