YFeO3　and　its　solid　solutions　responding　to　visible　light　were　prepared　by　a　self-propagating　combustion　method　using　yttrium　nitrate　and　iron　nitrate　as　precursors　and　glycine　as　a　fuel.　The　crystalline　phase　structures,　BET　surface　areas,　and　morphologies　of　as-prepared　samples　were　characterized　by　X-ray　powder　diffraction　(XRD),　N-2-sorption,　UV-Vis　diffuse　reflectance　spectroscopy　(UV-Vis　DRS),　scanning　electron　microscopy　(SEM),　and　transmission　electron　microscopy　(TEM).　The　results　show　that　the　purity　of　YFeO3　samples　prepared　via　self-propagating　combustion　method　can　be　effectively　enhanced　by　metal-doping.　The　average　crystalline　size　of　assynthesized　samples　is　55　nm.　Compared　with　YFeO3,　the　absorption　edge　of　the　solid　solution　samples　are　red　shifted.　The　YFeO3　and　its　solid　solutions　exhibit　noticeable　photocatalytic　activities　for　the　degradation　of　methylene　blue　(MB)　and　rhodamine　B(RhB).　And　Bi-doped　YFeO3　shows　the　best　performance.　Moreover,　the　YFeO3　solid　solutions　show　different　activities　for　the　degradation　of　different　dyes.
