Enhanced photocatalytic performance of porous MoS2 structures for methyl orange degradation in simulated sunlight

In this study, porous MoS2 nanoflowers (NFs) were synthesized using a simple hydrothermal method and tested for their photocatalytic efficiency in degrading methyl orange (MO) under simulated sunlight. The MoS2 NFs possess a hierarchical structure formed by ultrathin nanosheets, which provide a large surface area and active edge sites, enhancing light absorption and facilitating efficient charge separation. Photocatalytic experiments demonstrated an impressive degradation efficiency of more than 60% for MO dyes after 120 minutes of reaction with a degrading rate of 2.51 x 10-2 min-1. The enhanced photocatalytic performance is attributed to the high crystallinity, a large surface-to-volume ratio, and efficient charge carrier dynamics provided by the porous MoS2 nanoflower structure. These findings suggest that MoS2 nanostructures are highly promising as efficient and stable photocatalysts for practical applications in wastewater treatment under solar irradiation, offering potential for sustainable environmental remediation.
