@ARTICLE{, author = {}, title = {Effect of annealing temperature on structural, optical and catalytic properties of Cu-Zn ferrite nanoparticles }, volume = {24}, number = {2}, abstract ={In this research, Cu0.5Zn0.5Fe2O4 nanoparticles were prepared by citrateprecursormethod and under air-ambient annealing at 200, 400, 600°C. The structural features of samples were investigated by X-ray powder diffraction and FT-IR spectroscopy. The structural characterization of compounds, using X’Pert package and Fullprof program, is evidence for formation of a cubic structure (Fd-3m space group) with no presence of impurity phase that is emphasized by FT-IR data. Calculated values of crystallite size and unit cell parameter show a minimum for the sample annealed at temperature 200˚C. Band gap energies of samples have been estimated using absorption coefficient. under similar reaction conditions, the catalytic results show that the sample annealed at temperature 200˚C is the best catalyst for the CO and C2H6 oxidation due to smaller crystallite size. }, URL = {http://ijcm.ir/article-1-101-en.html}, eprint = {http://ijcm.ir/article-1-101-en.pdf}, journal = {Iranian Journal of Crystallography and Mineralogy}, doi = {}, year = {2016} }
