Nanostructured LaFeO3 and substituted LaZnxFe1-xO3(x = 0.01,0.05,0.1,0.2,and 0.3)perovskites were synthesized by the sol-gel auto-combustion method and used in
The composites comprising Fe-carbon nanotubes(CNTs)on TiO2 were prepared by a modified sol-gel method and characterized by nitrogen adsorption,scanning electron
