ZnFe2O4/?-Fe2O3/ZnO, the ternary transition metal oxide nanocomposite powder was successfully synthesized by facile coprecipitation method directly from metalorganic precursors within 4 h of processing time considerably shorter than other reported methods. To study post-synthesis thermal treatment effects on physical properties, calcination process applied at 500, 600, and 700 °C individually f...

The pyrolytic carbon of polymer adsorbent resin (SAP) is used as a waste source, which can be porous network via pyrolysis to remove surface sodium carbonate and other substances. In this paper, ZnFe2O4/nitrogen-doped composite was prepared using the template method. Through high-temperature carbonization crystallization inorganic elements, morphology showed uniform load characteristics. This w...

A magnetic recyclable Cu/ZnFe2O4 composite material was successfully prepared with easy-to-obtain raw materials. This obtained copper could be employed as efficient catalyst for both degradation of aromatic nitro compounds and C-N bond formation reactions without extra ligands. The reaction accomplished in 4 min high selectivity. variety N-aryl nitrogen-containing heterocycles products achieved...
