Spinel zinc ferrite (ZnFe2O4, ZFO) is a potential photoanode material for photoelectrochemical (PEC) water splitting because of its ideal bandgap (1.9–2.1 eV) and superior chemical stability in aqueous solutions. However, the low charge collection efficiency significantly hinders improvement PEC activity. Herein, we report an ultrafast effective flame activation route to e...

Due to the variability of cation occupancy octahedral and tetrahedral sites, spinel ferrites cobaltites are particularly interesting investigate activity trends in oxidation catalysis. Yet, preparation respective catalyst series remains challenging. We employed pulsed laser defect engineering CoFe2O4 nanoparticles water gradually alter sites by single pulses study its effect on cinnamyl alcohol...

Nanosized Ni ferrite has been prepared by an ecofriendly green synthesis approach based on the self-combustion method. In this route, egg white as a fuel was employed with two different amounts (3 and 10 mL). The XRD results display formation of stoichiometric NiFe2O4-type inverse spinel structure lattice parameter located at 0.8284 nm 0.8322 nm. Additionally, nickel ferrites’ typical crystalli...

We report the effect of surplus-Fe-content, and thermal annealing on properties sol gel auto-combustion synthesized Co 1–x Fe 2+x O 4 (x = 0.0–0.8) spinel ferrites. X-ray diffraction (XRD), magnetic measurements, Fourier transform infrared (FTIR) spectroscopy, Ultraviolet–visible (UV–Vis) are used to monitor excess Fe-content, dependence properties, correlation among them. XRD validates presenc...

The optical properties of multi-functionalized cobalt ferrite (CoFe2O4), cobalt zinc ferrite (Co0.5Zn0.5Fe2O4), and zinc ferrite (ZnFe2O4) nanoparticles have been enhanced by coating them with silica shell using a modified Stöber method. The ferrites nanoparticles were prepared by a modified citrate gel technique. These core/shell ferrites nanoparticles have been fired at temperatures: 400°C, 6...
