Abstract

To combat the ever-growing problems of environmental pollution and guarantee easy access to quality drinking water, research on and development of new materials for water treatment technologies and environmental remediation are of utmost importance. 2D disulfides MoS2 and WS2 are new emerging nanomaterials with great potential for environmental applications using solar light as an abundant energy source. Their unique electronic, photocatalytic and surface properties allow synergistic and simultaneous removal of both organic contaminants and heavy metals. However, owing to certain limitations such as extensive agglomeration and difficulty in recovering the materials from aqueous suspensions, such materials show limited applicability and performance in powder or suspension form. The proposed project aims to develop new routes for the preparation of MoS2, WS2 and MoS2/WS2 aerogels and their subsequent deposition on bacterial cellulose aerogel scaffolds, thus achieving macroscopic monoliths and porous nanostructured membranes with high surface area and multifunctional properties. By combining the visible-light driven photocatalytic and unique adsorptive properties of disulfide-based nanomaterials with the excellent mechanical and structural characteristics of bacterial cellulose membranes, we expect to obtain adsorptive filters and photocatalytic membranes with good performance towards removal of heavy metals and organic pollutants from contaminated wastewater and industrial effluents.
