Magnetic Hybrids and Supercapacitance

Magnetic Hybrids and Supercapacitance

We have synthesized superparamagnetic iron oxide nanoparticles using co precipitation method and developing nanoscrolls from various 2D materials using these superparamagnetic iron oxide nanoparticles. Carbon nanoscrolls are regarded as a tubular form of graphene sheets formed by rolling these sheets. Carbon nanoscrolls are important not only as these materials possess the mechanical and electronic properties of carbon nanotubes and graphene but also because they are expected to exhibit some novel electronic and optical properties. We have already synthesized GNSs from rGO sheets decorated with iron oxide nanoparticles through hydrothermal method.

The oil pollution has emerged as a widespread and extensive concern as it causes severe damages to marine and aquatic ecosystems. The technological use of nanoparticles has emerged as a novel solution for removing oil from spills and oil discharges. Iron oxide nanoparticles are known for their inherent low toxicity and magnetism, which not only allows the easy adsorption but also the easy separation of these nanoparticles from fluids. Graphite oxide can be used for oil spill removal due to its advantages of having higher adsorption capacity, higher adsorption rate, superior stability and recyclability. Inorder to control and recover GO, these can be hybridised with magnetic nanoparticles which improves both adsorption capacity as well as recovery. We are also working with oil spill removal using the synthesized magnetic hybrids.
