Synthesis of 2D Mos2 based nanocomposites and their application for the photocatalytic degradation of organic pollutants and hydrogen generation

Abstract

Two major problems that humanity faces in the current era are water contamination and energy shortages. The rapid industrialization and expansion of population are the major causes of these problems. This study presents the synthesis of 2D-MoS2 based heterostructures i.e. MoS2/Cu2O, ZnS/P-MoS2, BiOI/g-C3N4/MoS2 direct solar light-driven photocatalysts used for degradation of harmful pollutants and hydrogen generation coupled with benzyl alcohol oxidation. Characterization via XRD, FTIR, FESEM, HRTEM, and XPS revealed successful synthesis of heterostructures. Furthermore, PL, EIS, UV-vis DRS, and BET surface area analysis studies were also carried out. The photocatalytic activity of the as-prepared photocatalysts were investigated for the degradation of contaminants (IC, BG, and amaranth dye) and hydrogen generation coupled with benzyl alcohol oxidation under solar light illumination. The obtained results exhibited excellent photocatalytic efficiency of developed photocatalysts for wastewater treatment, green energy generation, and value-added compound production. newline
