“…ZnONPs is characterized by showing two peaks at at ca. 566 cm −1 and 1143 cm −1 (see Figure 4c), which have been assigned to A 1 -LO and E 1 -LO vibration modes of ZnO, respectively [45,46]. Both peaks are indicative that ZnONPs has a wurtzite-like crystal structure, as established by XRD.…”

The photocatalytic degradation of two quinolone-type antibiotics (ciprofloxacin and levofloxacin) in aqueous solution was studied, using catalysts based on ZnO nanoparticles, which were synthesized by a thermal procedure. The efficiency of ZnO was subsequently optimized by incorporating different co-catalysts of gC3N4, reduced graphene oxide, and nanoparticles of gold. The catalysts were fully characterized by electron microscopy (TEM and SEM), XPS, XRD, Raman, and BET surface area. The most efficient catalyst was 10%Au@ZnONPs-3%rGO-3%gC3N4, obtaining degradations of both pollutants above 96%. This catalyst has the largest specific area, and its activity was related to a synergistic effect, involving factors such as the surface of the material and the ability to absorb radiation in the visible region, mainly produced by the incorporation of rGO and gC3N4 in the semiconductor. The use of different scavengers during the catalytic process, was used to establish the possible photodegradation mechanism of both antibiotics.

“…Recently, Murumu et al reported a mixed magnetic behaviour of paramagnetic, superparamagnetic and ferromagnetic in Gd-implanted ion-beam-deposited ZnO films, which was attributed to the inhomogeneous distribution of Gd ions [15,16]. They also reported room temperature ferromagnetism in Erimplanted ZnO films indicating the origin associated with intrinsic defects in ZnO [17]. Chemical synthesis of nanostructured DMSs has been considered one of the effective ways to fabricate DMS with intrinsic ferromagnetism.…”
