摘要

介孔磁性纳米复合材料的合成概念是科学家和技术人员关注的焦点。本文采用纳米浇铸法制备了介孔NiFe2O4/还原性氧化石墨烯(rGO),以SBA-15为模板,采用初湿法制备了高有序介孔NiFe2O4。纳米浇铸后的NiFe2O4/SBA-15复合材料保持了有序的三维结构。采用热NaOH溶液溶解SBA-15模板,得到与母体SBA-15相似的无硅介孔结构NiFe2O4。采用XRD和FT-IR对其结构性能进行了表征。

Synthesis and structural characterization of light-weight ferrite-reduced graphene oxide composite
The synthetic concept of mesoporous magnetic nanocomposites is a centre of attraction for the scientists as well as technologists. In this work, mesoporous NiFe2O4/reduced Graphene Oxide (rGO) was synthesized based on the nanocasting method, highly ordered mesoporous NiFe2O4 was synthesized via the incipient wetness method using a mesoporous SBA-15 template. An ordered three-dimensional structure is preserved for the NiFe2O4/SBA-15 composite after nanocasting. To dissolve the SBA-15 template hot NaOH solution was used, and then the silica free mesoporous structure of NiFe2O4 was obtained similar to the parent SBA-15. The structural properties were determined by XRD and FT-IR spectroscopy.
