Gd　and　Sn　co-doped　BiFeO3　nanoparticles　were　synthesized　by　sol-gel　route　and　Bi0.95Gd0.05Fe0.93Sn0.05O3/Nitrogen　doped　graphene　nanohybrid　(BGFSO/NG,　where　NG:　1%,　2%,　3%,　4%,　5%,　6%)　were　synthesized　by　sprinkling　BGFSO　nanoparticles　and　NG　into　ethanol　solution　followed　by　thermal　drying.　Structural　and　morphological　properties　of　BiFeO3　(BFO)　nanoparticles,　BGFSO　nanoparticles,　NG　and　BGFSO/NG,　were　investigated　by　X-ray　diffraction　(XRD)　and　scanning　electron　microscopy　(SEM).　The　crystallite　size　BGFSO　nanoparticle　is　about　20　nm.　The　photocatalytic　activities　of　the　as-prepared　BiFeO3　(BFO)　nanoparticles,　BGFSO,　NG　and　BGFSO/NG　nanohybrid　were　measured　by　the　degradation　of　methyl　orange　(MO)　under　simulated　sunlight　irradiation.　BGFSO/N-G　nanohybrid　shows　enhanced　photocatalytic　activity.　The　improved　photo　catalytic　activity　is　attributed　to　the　effective　transfer　of　photogenerated　electrons　from　nanoparticles　NG　nanosheets,　consequently　leads　to　an　increased　availability　of　h　+　for　the　photocatalytic　reaction.　Additionally,　hydroxyl　(center　dot　OH)　radicals　were　detected　by　the　photoluminescence　method　through　terephthalic　acid　(TPA)　as　a　probe　molecule　and　are　found　to　be　generated　on　the　irradiated　BGFSO　and　BGFSO/NG.
