Nanocellulose/Polyvinyl Alcohol Hydrogel with Adsorption and Photocatalytic Properties

Abstract

Multifunctional Nanocellulose/Polyvinyl alcohol hydrogels with adsorption and photocatalytic properties towards an anionic dye Metanil Yellow (MY) was investigated. Office wastepaper was used as the raw material for synthesizing nanocellulose. The hydrogels were fabricated via the sol-gel method. The adsorption and photocatalytic properties of the hydrogel were evaluated under dark and sunlight irradiation respectively. Photo-stability of the hydrogels was studied by evaluating their recyclability efficiency. This study clearly reveals the potential application of the present system for anionic MY dye degradation.
