摘要：

ZnFe2O4-graphene　aerogels　(ZnFe2O4/GAs)　composites　are　prepared　by　two-step　method　(hydrothermal-calcination).　Highly-purified　ZnFe2O4　nanoparticles　are　dispersed　uniformly　on　three-dimensional　(3D)　GAs　substrate.　The　mass　loading　of　ZnFe2O4　in　ZnFe2O4/GAs　composites　is　89.3%.　Compared　with　pure　ZnFe2O4　sample,　the　ZnFe2O4/GAs　composites　exhibit　much　higher　irreversible　capacity　of　1449.4　mAh　g(-1)　and　enhanced　cycling　stability　(1049　mAh　g(-1)　at　100　mAg(-1)　after　100　cycles).　The　improved　electrochemical　performance　of　the　ZnFe2O4/GAs　composites　could　be　attributed　from　the　synergetic　effect　between　3D　conductive　GAs　and　nanostructured　ZnFe2O4.　(C)　2017　Elsevier　B.V.　All　rights　reserved.
