Green Nanocomposites

Considerable interest has been focused recently on the application of magnetic separation technology to solve the various environmental problems. Magnetic carbon-nanocomposites have unique magnetic separation and potential adsorption for pollutants. Carbon matrices avoid the agglomeration of iron oxide nanoparticles and magnetic separation is a substitute to filtration or centrifugation as it avoids the loss of materials. Magnetic separation is quick and operative technique.Functionalized magnetic nanocomposites have distinct advantages over conventional materials due to their selective absorptivity, strong magnetic responsiveness, favorable water dispensability and benign biocompatibility. The semiconductor based carbon-nanocomposite have revealed high ability for the catalytic degradation of contaminants from aqueous segment. While, application of photocatalysis using heterogeneous semiconductor seems to be most pleasant mean and found to be inexpensive, non-toxic, broad absorption spectra with higher absorption coefficients and capability for multi-electron transfer.
