Removal and degradation of mixed dye pollutants by integrated adsorption-photocatalysis technique using 2-D MoS/TiO nanocomposite.

Two-dimensional (2D) Molybdenum disulfide (MoS) has become one of the most exciting areas of research for adsorbents due to its high surface area and abundant active sites. Mainly, 2D MoS show promising removal of textile dye pollutants by adsorption process, but it show high affinity for anionic type of dyes, that limits its performance in mixed dye pollutants treatment. Herein, we demonstrate an integrated approach to remove mixed dye pollutants (anionic and cationic) concurrently by combining adsorption and photocatalysis process.

Microwave- and Formaldehyde-Assisted Synthesis of Ag-AgPO with Enhanced Photocatalytic Activity for the Degradation of Rhodamine B Dye and Crude Oil Fractions.

The release of crude oil and water-soluble dyes into our marine environment is a major global problem. An efficient semiconductor Ag-AgPO photocatalyst was synthesized using formaldehyde as a reducing agent to form surface active Ag on AgPO under microwave radiation for heating, and its potential in destroying environmental pollutants has been examined. The diffuse reflectance spectroscopy of Ag-AgPO revealed an enhanced absorption in the visible light region.
