Abstract

MoSe2, a significant component within the class of two-dimensional transition metal
dichalcogenides (TMDCs), boasts a diverse set of photocatalysis characteristics. Herein, we
report a simple hydrothermal technique to synthesis MoSe2/MnO2 nanocomposites with
controllable morphologies size with enhanced photocatalytic activity. The obtained
nanocomposite was confirmed by the analysed peaks of MoSe2/MnO2 observed in Powder Xray
diffraction (13.6o,18.1o,37.5o), infrared spectra (495 cm-1, 645 cm-1, 1410 cm-1), UV-Vis
spectra (506 nm, 640 nm, 748 nm) and the narrowing band gap 1.96 eV, 2.52 eV and 2.73
eV. Due to the efficient separation of photogenerated electron-hole pairs facilitated by the
rapid transfer of photogenerated electrons by the addition of MnO2, the MoSe2/MnO2
composite demonstrates significantly enhanced solar-driven photocatalytic performance and
excellent stability in degrading Direct Yellow (DY), a common pollutant found in industrial
effluents. The MoSe2/MnO2 nanocomposite photocatalytic activity was found to be 1.2 to 1.6
times higher than that of its individual components of MoSe2 and MnO2, indicating
synergistic effects leading to enhanced performance. This underscores its considerable
potential for environmental remediation, offering a promising approach for the degradation of
harmful industrial chemicals present in wastewater using sunlight.
