“…The isomer shift of the paramagnetic doublet is very low. Similar isomer shifts have been reported for Fe 3+ tetrahedral species with a highly covalent character. − Similar isomer shifts have also been reported for mixed valent Fe 3+ -Fe 4+ systems. However, we believe that the assignment to a Fe 3+ species of a markedly covalent character is more plausible because the present synthesis conditions are not oxidant enough as to promote the formation of Fe 4+ .…”

In this work, Fe 2 O 3 -Ni, Fe 2 O 3 -Ni-Pd, MgO-Ni, and MgO-Ni-Pd nanoparticles were synthesized, characterized, and used for the degradation of florfenicol (FLO). The main goals were to compare the removal capacity of Fe 2 O 3 -Ni and MgO-Ni nanocatalysts and evaluate the effect of Pd incorporation on Fe 2 O 3 -Ni and MgO-Ni nanoparticles on the degradation of FLO by heterogeneous Fenton(-like) and photo-Fenton(-like) processes. The adsorption and degradation processes of FLO were assessed, determining that the latter process is the principal mechanism for FLO degradation. Through the heterogeneous photo-Fenton process, the antibiotic was 78 and 44% removed using the Fe 2 O 3 -Ni and MgO-Ni nanocatalyst, respectively, improving degradation by 22% when Pd is incorporated into both nanostructures. FLO degradation occurs because of the generation of hydroxyl and superoxide radical and holes in the interface and the Fenton reaction with Fe and Mg present in the nanoparticles. Finally, the main organic intermediates produced during the degradation were identified, allowing the proposal of a degradation pathway. Thus, heterogeneous Fenton(-like) and photo-Fenton(-like) processes using nanoparticles as solid phase catalysts are an excellent alternative to FLO degradation from water, especially considering the easy recovery of the nanoparticles through a simple separation process such as filtration.

“…These are also used in bioapplications along with various optical applications. , Very recently, these oxide glass-ceramics have also been reported for catalytic applications which lead to many more applications such as self-cleaning, hydrophobic, antibacterial, and cleaning of other organic pollutants. − For photocatalysis, glass-ceramics should have a photocatalytic active semiconductor crystal phase in a glassy matrix. There are few articles reported in this direction. − Crystals such as TiO 2 and ZnO are embedded in glassy matrices using controlled heat treatments and are also reported for photocatalysis. , …”

SrO-Bi2O3-B2O3 (SBBO) transparent glasses were fabricated via the conventional melt quenching technique. X-ray diffraction (XRD) was carried out to confirm the glassy nature. Differential scanning calorimetry (DSC) was utilized to gain knowledge about the crystallization temperature, and following that glass samples were heat-treated to achieve crystallinity. The obtained values of the glass transition temperature (T g), the onset of crystallization temperature (T cr), and the peak crystallization (T p) temperature are 408, 438, and 440 °C, respectively. The glasses were heated at 440 °C for 30 min, 1 h, and 2 h to form glass-ceramics. The SrBi2B2O7 phase was formed during 1 h of heat treatment of the glasses. Studies of active vibration modes were done by Raman spectroscopy for SBBO glass and glass-ceramic samples. Piezocatalysis experiments were carried out for the removal of organic pollutants with Methylene Blue (MB) dye as a model dye, and the obtained maximum dye degradation was 51% with a kinetic rate of 0.002 min–1 under 240 min of ultrasonication. Experiments were repeated for 5 cycles to confirm the repeatability, and different dyes were used for degradation to confirm the reliability of the prepared glass-ceramic sample. Furthermore, Vigna radiata seeds were used to study the byproduct of dye that had been degraded for the assessment of phytotoxicity.
