Removal and degradation of mixed dye pollutants by integrated adsorption-photocatalysis technique using 2-D MoS2/TiO2 nanocomposite

Two-dimensional (2D) Molybdenum disulfide (MoS 2 ) has become one of the most exciting areas research for adsorbents due to its high surface area and abundant active sites. Mainly, 2D MoS show promising removal textile dye pollutants by adsorption process, but it affinity anionic type dyes, that limits performance in mixed treatment. Herein, we demonstrate an integrated approach remove (anionic cationic) concurrently combining photocatalysis process. We synthesize /TiO nanocomposites different weight percentages 2.5, 5, 10, 20, 30 50 wt% pre-synthesized flower-like nanoparticle a two-step hydrothermal method. new process two-stage adsorption/photocatalysis using (Stage-I) low (Stage-II) nanocomposites. The proposed 50% 2.5% coated TiO , respectively showed complete methylene blue ?5 times faster than conventional single-stage (adsorption or photocatalysis) water treatment Furthermore, feasibility method testified, which excellent even doubling pollutant concentration. This work brings deeper insight into understanding morphology concentration 2-D nanocomposite tackling possibilities applying dyeing industries wastewater plants. • composite synthesized % .
