In the present work, we synthesized La/Cu/Zr trimetallic nanoparticles (TNPs) by microwave method, which is applied as an effective nanophotocatalyst for the removal of a ampicillin antibiotic from aqueous media. The prepared nanomaterial was characterized by Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The experimental results showed that prepared nanoparticles have high photodegradation tendency for the removal of ampicillin antibiotic from the aqueous solution. The pseudo-first-order equation represents the better kinetics of the photocatalytic process. The feasibility of ampicillin antibiotic adsorption onto La/Cu/Zr TNPs was also studied and the results showed that the adsorption was supported with spontaneous photodegradation process. A photocatalytic degradation 86% of the antibiotic has been observed. [ABSTRACT FROM AUTHOR]

Iron molybdophosphate (FeMoPO) nanoparticles have been fabricated using simple co-precipitation method. The nanoparticles showed promising ion exchange nature with ion exchange capacity of 1 meq g − 1 .The synthesis on nanoparticles has been ascertained by characterizing the material using various techniques including Fourier transform infrared spectroscopy (FTIR) scanning electron microscopy (SEM) and transmission electron microscopy (TEM). To investigate the ion exchange behavior of FeMoPO nanoparticles its physicochemical properties has been studied in detail such as thermal stability, pH titrations, and elution behavior. FeMoPO nanoparticles have been explored as potential candidature for photocatalytic remediation of malachite green (MG) dye from aqueous system. It has been observed that FeMoPO nanoparticles efficiently photodegraded 77% of hazardous MG dye in 5 h of photo-exposure. [ABSTRACT FROM AUTHOR]
