The inverse spinel nanocrystalline pure and doped nickel ferrite particles were synthesized by co-precipitation method. The thick films of both pure and doped nickel ferrite nanoparticles were prepared by coating the material on glass substrate via screen printing method. The XRD was used to confirm cubic, crystalline nickel ferrites. The scanning electron microscopy confirms nanosized, cubic nanoparticles of nickel ferrite, and their morphology was investigated. The energy-dispersive spectroscopy was used to comprise elemental composition for pure and doped ferrites. Transmission electron microscopy was attributed for investigation of surface morphology, crystal structure identification of nickel ferrites. The FT-IR was used to find the vibrational frequencies, symmetric, asymmetric stretching and bending modes of metal oxide linkage. The thick films of nickel ferrite were employed for sensing phenomenon of gases such as LPG, NO 2 , CH 3-OH, C 2 H 5-OH, NH 3 and petrol vapours. The pure nickel ferrite showed excellent results for ammonia and nitrogen dioxide gases up to 90.42 and 86.42, respectively. Manganese-and cobalt-doped ferrites were excellent for ammonia and petrol vapours. Modified nickel ferrite effect of dopants cobalt and manganese was investigated. Pure and doped ferrites showed excellent response and recovery for ammonia, NO 2 , petrol vapours and LPG gases.

In this work, Ru-doped nickel ferrites (NiFe 2 O 4 ) were synthesized by a chemical co-precipitation method. Subsequently, they were annealed at different temperatures. The crystallinity of the samples was evaluated using X-ray diffraction and the morphology of the samples was investigated by scanning electron microscopy and transmission electron microscopy. Dielectric constants and dielectric loss were studied. Ru-doped nickel ferrite samples showed relatively low dielectric constant and loss. Also, the dielectric constant and loss decreased with increasing annealing temperature. Vibrational sample magnetometer analysis shows the hysteresis loop of a soft magnetic nature and the relevant parameters ( M r, M s and H c ) have low values that confirmed the nature of the material. Subsequently, gas sensors were fabricated to study hydrogen-sensing properties. The gas sensors showed a response to hydrogen gas at a low temperature (100 °C) with selective response in the presence of NH 3 and C 2 H 5 OH gases. The reasons for electrical, magnetic, and sensing behavior of the samples were discussed in detail.

“…12 Multiwalled carbon nanotubes (MWCNTs) possess many topological defects in the tube walls so that they have more active sites on the surface than other graphite carbon materials. 13 To the best of our knowledge, NiFe 2 O 4 /MWCNT nanocomposites have been reported previously in the application of gas sensing, 14 for the determination of the voltammetric behaviour of dopamine, 15 and in magnetic hyperthermia, 16 but their electrocatalytic activities for both the ORR and OER have been seldom reported.…”

It is of great concern to explore new electrocatalysts for the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER). In this study, spinel NiFe2O4 nanoparticles cross-linked with the outer walls of multiwalled carbon nanotube (MWCNT) were successfully prepared by a peaceable, scalable hydrothermal method. The as-synthesized NiFe2O4/MWCNT nanohybrid shows not only a better ORR catalytic activity than pure NiFe2O4 and MWCNT, but also a close four-electron reaction pathway. Meanwhile, NiFe2O4/MWCNT nanohybrid exhibits much higher OER catalytic activity as compared to NiFe2O4, MWCNT and the commercial Pt/C in terms of the onset potential and current density. Moreover, the NiFe2O4/MWCNT nanohybrid demonstrates the preeminent long-term durability measured by the current-time chronoamperometric test for both ORR and OER, which evidently outperforms the commercial Pt/C. The excellent bifunctional electrocatalytic activities of NiFe2O4/MWCNT nanohybrid are attributed to the strong coupling between NiFe2O4 nanoparticles and MWCNT as well as the network structure.
