A 100?mM H2O2 solution was decomposed to 97.4%. The surface morphology of the cobalt ferrites remains unchanged after the catalytic decomposition of H2O2. The synthesized cobalt ferrites can be used in Fenton processes as stable magnetic catalysts....
The plant extracts of ginger root and cardamom seeds are utilized for the auto-combustion, green synthesis process to obtain the nanoparticles. The X-ray diffraction patterns confirm the spinel structure and the average particle size in the range of 14–20nm for the nano ferrites. Energy ...
The aim of the experiment was a green synthesis of cobalt nanoparticles from the aqueous extract ofZiziphora clinopodioidesLam (CoNPs) and assessment of their cytotoxicity, antioxidant, antifungal, antibacterial, and cutaneous wound healing properties. The synthesized CoNPs were characterized using diffe...
Scheme of synthesis of the CT-Fe beads. The magnetite is formed during the beginning of nucleation under alkaline conditions. Full size image Figure 2b depicts the metal-organic structures of the hybrid composite material, synthesized by the iron oxide dispersion in the chitosan network (CT-Fe)....

Catalytic fields include the use of mainly cobalt, nickel, copper, and zinc ferrites, as well as their mixed-metal combinations with Cr, Cd, Mn and sometimes some lanthanides. The ferrite nanomaterials are obtained mainly by co-precipitation and hydrothermal methods, sometimes by the sonochemical ...
A variety of spinel ferrites have been introduced as attractive photocatalysts due to their activity in visible region; reduced bandgap of ferrites is of great importance because narrow bandgap enables good photocatalytic activity in the visible region. Doping of some elements in ferrites help reduce ...
Preparation and magnetic properties of Ba–Co[sub 2]Z and Sr–Zn[sub 2]Y ferrites. We have prepared Ba–Co[sub 2]Z and Sr–Zn[sub 2]Y ferrites by mixing SrCO[sub 3] (BaCO[sub 3]), Co[sub 2]O[sub 3] (ZnO), and Fe[sub 2]O[sub 3] and calcina... Chen,In-Gann,Hsu,...
