Improvement of Nanosized CuO-Fe2O3/cordierite System by Li2O-treatment for wastewater treatment
A mixture of 10 wt% CuO-10 wt% Fe2O3 supported on cordierite were prepared by wet impregnation. The as-prepared solids doped with Li2O (0.75-3 mol %) were calcined at 500-900 ºC. The crystalline phase, morphology, and surface area were investigated by XRD, HR-TEM and N2-adsoprtion-desorption. Moreover, their photocatalytic activities of samples calcined at 700°C on the degradation of phenol wer...
متن کاملPreparation of Promoted Ni0.1Co0.9Fe2O4 Ferrite Nanoparticles and Investigation of Its Catalytic Activity on Decomposition of H2O2 and Optical Characterization of Pure Ni0.1Co0.9Fe2O4
Pure and ZnO-doped Ni0.1Co0.9Fe2O4 catalyst were prepared by co-precipitation method and thermal decomposition in air calcinated at 400-700°C and that treated with different amounts of zinc nitrate (0.46-2.25 w% ZnO). X-ray powder diffractometry, scanning electron microscopy (SEM) and BET analysis of nitrogen adsorption isotherms investigated the crystalline bulk structure and the surface area ...

متن کاملCatalytic Decomposition of H2O2 on MnFe2O4 Nanocomposites Synthesized by Various Methods in the Presence of Silicate and Zeolite Supports
In this research iron manganese oxide nanocomposites were prepared by co-precipitation, sol-gel and mechanochemical methods by using iron (III) nitrate, iron (II) sulfate and manganese (II) nitrate as starting materials. These nanocomposites were prepared in the presence of various catalyst beds. The polyvinyl pyrrolidon (PVP) was used as a capping agent to control the agglomeration of the nano...
