Synergistic exploration of dye degradation and pulse photoresponse using MoS2 nanosheets: Towards sustainable remediation and optoelectronic advancements

Abstract

Two essential areas of research with important implications for environmental cleanup and optoelectronic device applications are dye degradation and the comprehension of the pulse photo-response of transition metal dichalcogenide (TMDC) materials. Using MoS2 Nanosheets, this study evaluates the pulse photo-response characteristics of dyes and their degradation mechanisms. The article focuses into the effectiveness of MoS2 materials in dye removal as well as their function in photocatalytic degradation processes. Additionally, the MoS2 nanosheets are easy to utilise in solutions containing methylene blue (MB) and can be used as a high-performance recyclable photocatalyst to photodegrade organic dyes like methylene blue (MB) in around 120 min when exposed to light. The pulse photoresponse behaviour of MoS2 Nanosheets (NSs) is also investigated, with an emphasis on their distinct charge carrier dynamics and potential uses in ultrafast photodetectors. The working electrodes constructed from MoS2 nanosheets demonstrate an obvious photovoltaic effect with a photocurrent of 6.920 A/cm2 at zero bias and 100 mW/cm2 of polychromatic light. Due to optimal conditions, the maximum photoresponsivity of 5.669 mA/W and Detectivity of 7.708 × 108 Jones is achieved. The intention is to provide details on the way dye degradation and pulse photo-response interact synergistically in MoS2 nanosheets and highlight their potential for improved optoelectronic devices and environmentally friendly remediation.
