Construction of a ternary g-C3N4/MoS2/MWCNTs nanocomposite for the enhanced photocatalytic performance against organic dye.

The enhanced photocatalytic process of GMNT NCs was achieved by wet impregnation. The resulting sample was examined using numerous analytical techniques to determine its composition, morphology, structure, and optical properties. GMNT photocatalyst showed impressive photocatalytic degradation efficiency (91.75%) over RhB dye in 100 min, when exposed by visible illumination. The photoreaction rate constant of GMNT ternary PCs (0.0233 min⁻¹) was 6.2 times faster than bare GCN (0.0037 min⁻¹), GMS (0.0055 min⁻¹), and GCNT (0.0124 min⁻¹) against RhB dye. Besides, they have considerable stability against RhB dye degradation after five cycles. A trapping experiment with a variety of scavengers also reveals that photogenerated charge carriers hole pair and ^⋅O₂⁻ radicals play a prominent role in the photodegradation process. GMNT nanocomposite has been shown to enhance photocatalytic performance by suppressing e⁻–h⁺ pair separation and recombination efficiency. Hence, GMNT PCs have shown high potential for various environmental applications, including wastewater treatment. [ABSTRACT FROM AUTHOR]
