“…These peaks appeared at 2θ = 29.8°, 35.1°, 38.07°, 42.65°, 53.09°, 56.56°, and 62.09°, which could be imputed to (220), (3 1 1), (2 2 2), (4 0 0), (4 2 2), (333), and (4 4 0), respectively. The spinel phase’s development is shown by the strong peak visible at the (311) plane 50 . The highest peaks slightly migrated towards lower angles as the Ag + content rose (when x = 0.5), confirming the Ag + substitution for Zn 2+ .…”

Silver-zinc-nickel spinel ferrite was prepared by the co-precipitation procedure with the precise composition Ag0.1Zn0.4Ni0.5Fe2O4 for bolstering pollutant removal effectiveness while upholding magnetic properties and then coated with a mesoporous silica layer. The surface characteristics and composition of Ag0.1Zn0.4Ni0.5Fe2O4@mSiO2 were confirmed using EDX, FT-IR, VSM, XRD, TEM, SEM, and BET methods. The surface modification of Ag-Zn-Ni ferrite with a silica layer improves the texture properties, where the specific surface area and average pore size of the spinel ferrite rose to 180 m2/g and 3.15 nm, respectively. The prepared spinel ferrite@mSiO2 has been utilized as an efficient adsorbent for eliminating methyl green (MG) and indigo carmine (IC) as models of cationic and anionic dyes from wastewater, respectively. Studying pH, Pzc, adsorbent dosage, dye concentration, and temperature showed that efficient removal of MG was carried out in alkaline media (pH = 12), while the acid medium (pH = 2) was effective for IC removal. Langmuir isotherm and pseudo-second-order kinetics were found to be good fits for the adsorption data. Both dyes were adsorbed in a spontaneous, endothermic process. A possible mechanism for dye removal has been proposed. The adsorbent was effectively recovered and reused.

“…12 (a-f). The relation among magnetization (µB) and applied magnetic eld (Oe) is provided by hysteresis loops (Tanveer et al, 2022). Saturation magnetization, coercivity, remanence magnetization, and squareness ratio of the materials were obtained by these hysteresis loops, which are presented in Table 4.…”

Cobalt based nanoferrites Co 1 − x Cu x Ce y Fe 2−y O 4 Where nano ferrites produced through citrate gel auto combustion technique and their structural and topographical studies were inspected through x-ray diffraction technique and eld emission scanning electron microscope. The structural analysis con rms the prepared nano ferrites having single-phase cubic spinel, along Fd3m space group. Crystalline size of the synthesized samples found 20-26 nm calculated by Debey Scherrer formula. Catalytic activity of the samples con rmed by dye degradation studies of methylene blue and acid red dye degradation. Magnetic behavior of the materials measured by a vibrating sample magnetometer, saturation magnetization gradually decreases as increasing Cu and Ce content and found to be 26 to 18 emu/gm. Electrical properties were measured by LCR meter.

“…Generation, transmission, and separation proficiency of charge carriers can be studied via photoluminescence (PL) analysis. If the PL emission intensity is higher, then it shows recombination of charge carriers that is high and fast [29]. PL spectra of different photocatalysts at the excitation wavelength of 325 nm are depicted in Figure 6.…”

Enhanced Photocatalytic Performance of Ag3PO4/Mn-ZnO Nanocomposite for the Degradation of Tetracycline Hydrochloride

et al. 2022

Using sustainable photocatalysts, photocatalytic degradation has emerged as one of the viable strategies to combat water pollution through eco-friendly and cost-effective means. Visible-light-active Ag3PO4/Mn-ZnO nanocomposite photocatalysts were produced in this study using a simple hydrothermal method and varied concentrations of Ag3PO4 to Mn-ZnO ranging from 0 to 5 wt percent. X-ray diffraction, scanning electron microcopy, energy-dispersive X-ray, transmission electron microscopy, UV–visible spectroscopy, Fourier transform infra-red spectrophotometer, and photoluminescence spectroscopy were used to examine the structural, morphological, and optical properties of synthesized materials. Visible light was used to test the photocatalytic activity of produced Ag3PO4/Mn-ZnO photocatalysts for the breakdown of tetracycline (TC) hydrochloride. In comparison to the other samples, the 3% Ag3PO4/Mn-ZnO nanocomposite exhibited superior activity as a result of improved visible light absorption and suppressed charge carrier recombination. In addition, this sample demonstrated good stability of TC in an aqueous environment after five consecutive cycles. This research will enhance the scope of photocatalysis for environmental applications.
