| Abstract: | A sol-gel method was applied to synthesize
Bi1-xMxFeO3 (M = Mg, Al, Y) ceramic materials.
Subsequently, these materials were structurally characterized by applying
Rietveld refinement techniques. The magnetic properties of the synthesized
materials were determined by SQUID measurements and their optical properties
(band-gap) were determined by applying diffused reflectance (DR) techniques. The
low band-gap nature of these materials enabled to them exhibit photocatalytic
activity and accordingly 2% Y doped BiFeO3 samples exhibited higher
photocatalytic effect (18% compared to 14% for undoped). Under identical
conditions, TiO2 standard exhibited only 7% degradation indicating
superior properties of cation-doped bismuth ferrites. |
