Sustainable multilayer biomass carbon and polymer hybrid column as potential antibacterial water filter.

Stipulation of fresh water for domestic use without any microbial, organic and inorganic contaminants is of high need. Sustainable, efficient, cost-effective and robust water purification technologies is of high need and it can be achieved using nanomaterials and their composite. Nanostructured graphene has unique properties like high surface to volume ratio, higher absorbability, reusability with minimal chemical alterations, and low cytotoxicity.

MnO encapsulated electrospun TiO nanofibers as electrodes for asymmetric supercapacitors.

We report a facile technique to fabricate manganese dioxide (MnO) encapsulated titanium dioxide (TiO) nanofiber heterostructure for its use as an electrode material in aqueous electrolyte based asymmetric supercapacitor (SC). MnO coated TiO nanofibers, prepared by electrospinning and post-hydrothermal process exhibited superior electrochemical properties in aqueous NaSO electrolyte. The MnO shell with average thickness of approximately 10 nm contributed to the high electrochemical performance for charge storage by redox reaction and intercalation mechanisms, while the anatase phase TiO core provided an easy pathway for electronic transport with additional electrochemical stability over thousands of charge-discharge cycles.
