Synthesis and structural characterization of light-weight ferrite-reduced graphene oxide composite

Abstract

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.
