Advanced Energy and Sustainability Research. https://doi.org/10.1002/aesr.202400213.2699-941210.1002/aesr.202400213https://academica-e.unavarra.es/handle/2454/52397The exaltation of the photodegradation performance of dichalcogenide MoS2 grown on top of silver nanoparticles (Ag-NPs) is reported on. The fabricated MoS2 nanosheets nucleate vertically from Ag-NPs seeds, enabling the growth of both metallic and semiconductor phases 1T/2H-MoS2. Findings reveal remarkable enhancement of the Raman scattering and an exceptional broadband optical absorption attributed to plasmonic effects induced by the presence of both metallic 1T-MoS2 and Ag-NPS at 2H-MoS2 interfaces. To leverage this effect, photodegradation tests are conducted to remove methyl orange pollutant. Notably, results reveal a significant increase in photodegradation efficiency and rate constant, reaching up to 120% and 550% over pristine 2H-MoS2, respectively. This finding underscores the role of Ag-NPs and 1T-MoS2 tandem to unlock the superior photodegradation properties of vertically aligned 2H-MoS2 toward methyl orange, paving the way for the development of dichalcogenide-based hybrid photocatalyst for wastewater treatment and environmental remediation.application/pdfeng© 2024 The Author(s).
