“…The diffraction planes were matched well with standard data (ICDD# 00-010-0325). The matching of data confirmed the synthesis of dysprosium substituted nickel-cobalt ferrites [22]. The value of lattice constant was also calculated using cell software and found to be 8.67 Å [23].…”

High-quality nanostructure of dysprosium substituted nickel-cobalt ferrite and their composite with reduced graphene oxide (rGO) were synthesized. The structuraland photocatalytic properties of prepared samples were studied. The XRD and FTIR analysis confirmed the FCC spinel structure. The calculated average crystallite size of nanoparticles was around 7.8 nm. The bandgap energy of synthesized composition was found to be 2.27 eV. The uniform dispersion of nanoparticles on the graphene nanosheets were confirmed by the FESEM analysis. The photocatalytic efficiency of nanoparticles and their composites with rGO was studied for degradation of methylene blue (MB) under visible light irradiation. It was found that nanocomposite exhibited high photocatalytic activity (72.7%) as compared to Dy +3 substituted Ni-Co ferrite nanoparticles (52.4%). This enhanced photocatalytic activity can be attributed to the presence of graphene, which enhances the stability of nanocomposite and reduces the recombination of charge carriers.

This research work explores the effect of sintering temperature on morphology and magnetic properties of aluminum substituted gadolinium iron garnet Gd 3 Al x Fe 5−x O 12 (x = 2). Sol-gel autocombustion method is adopted to prepare Gd 3 Al x Fe 5−x O 12 , and further sintered at 900, 1000, and 1100 °C. X-ray diffraction (XRD) confirms the formation of garnet phase structure. Fourier transformation infrared ray further stands with result of XRD that reveals the presence of garnet phase. Field emission scanning microscope analysis shows the formation of average grain size 4, 6, and 13 nm for 900, 1000, and 1100 °C, respectively. Vibrating sample magnetometer results show that the coercivity decreases with increases in temperature, which indicates that this material can be used in switching devices. The calculated value of microwave operating frequency reveals that these materials can be used in ultrahigh-frequency region.

The secondary pollution from hydrometallurgical recycling of lithium ion batteries (LIBs) is a concern affecting the process sustainability. This study explores the reuse of two LIB processing streams (iron-sludge and Mn-stripping effluent) to produce magnetic nanosized sorbents. A surfactant-autoclave synthesis was carried out to obtain CuFe2O4 (15 nm) from synthetic precursors, and Cu(0.48)Co(0.40)Mn(0.10)Ni(0.02)Fe2O4 (12 nm) from iron-sludge. Both products exhibited crystallite size less than 20 nm and a narrow size distribution. These materials were used for sorption tests on synthetic solutions and pretreated Mn-stripping effluent. Mn preferential sorption (≈ 16 mg/g) versus Co, Li and Na was noticed. Mn and Co removal from pretreated effluent increased using the recycled material (Mn 100%, Co 70%) rather than CuFe2O4 (Mn 91%, Co 59%). Furthermore, single-phase nanocrystalline Mn(0.63)Co(0.35)Ni(0.02)Fe2O4 ferrites were entirely resynthesized from the two LIB streams by an ultrasound-surfactant-microwave treatment. A broader crystallite size distribution was achieved, compared to autoclave materials. When dried at 100 °C sizes ranged up to 57 nm, while sintering at 700 °C to 98 nm. Distinct physical-and chemical properties (i.e. magnetization, porosity, sizes) were studied to assess either the effect of the advanced hydrothermal routes and of the starting materials on the final products.
