Abstract Bio derived nanocellulose possesses versatile properties, which are very worthwhile for advanced functional applications. Nanocellulose i.e. nanofibers and nanocrystals can be applied in the form of solution, suspension, ink or nanomaterials in composites, nanocomposites, coatings and films. These forms of nancellulose are found for the development of hydrogels, aerogels, electrodes, adsorbents, packaging films, membranes, nanopapers, filters, supercapacitors, electrodes, electrolytes, rheology modifiers, food additives, scaffolds, and biomaterials/formulations for biomedical and tissue engineering. This paper, categorically reviews and discusses the potential of composite, nanocomposite and hybrid materials obtained from nanocellulose for water

treatment and purification. It reviews the extraction of nanocellulose such as cellulose nanofibers, cellulose nanocrystals and bacterials nanocellulose and their physicochemical properties. The emphasis has been given on the nanocellulose based adsorbents, absorbents, flocculants, nanopapers, membranes, photocatalysts etc. It is seen that nanocellulose based various functional nanocomposite and hybrid materials have huge potential for the extraction of metal ions and organic dyes from water, removal of organic contaminants, virus, bacteria, turbidy and chemical oxygen demand from wastewater stream, separation of oil/water mixture, and photocatalytic degradation of organic contaminants in water. The comparative analysis of cellulose nanomaterials for all the above applications are presented graphically to understand the relation between types of materials and their potential for water purification by removing different contaminant; as well as its proton conductivity for prospective application in fuel cells.
