Magnetic　NiFe2O4　nanoparticles　were　synthesized　via　a　hydrothermal　and　calcination　process.　The　obtained　NiFe2O4　with　an　average　diameter　of　17.8　nm　and　specific　surface　area　of　76.2　m(2)　g(-1)　is　first　used　as　a　photocatalyst　for　hydrogen　production,　and　exhibits　an　obvious　visible-light-driven　photoactivity,　and　therefore　is　promising　in　the　practical　application　as　a　magnetically　separable　and　visible-light-responsive　photocatalyst　without　Pt-loading.　(C)　2012　Elsevier　B.V.　All　rights　reserved.
