Two-dimensional (2D) monolayered materials, such as Janus MoSH, offer significant potential for improving water splitting efficiency and renewable hydrogen production. While traditional catalysts like Pt face limitations due to rarity and cost, 2D materials present advantages like high catalytic activity and sustainability. The unique electric field in 2D ML-MoSSe material and the structural stability of Janus MoSH monolayer provide insights for enhancing catalytic efficiency. Despite challenges in electrocatalytic mechanisms, ongoing research focuses on optimizing the performance of Janus 2D materials for better photocatalytic capabilities. Structural stability tests, including phonon dispersion spectra and AIMD simulations, confirm the stability and thermal resilience of Janus MoSH. Calculations of cohesive energy further support the energetically stable nature of the MoSH monolayer. Continued investigations aim to unravel the electrocatalytic properties of 2D Janus MoSH, paving the way for sustainable and efficient electrocatalysts in the field of renewable hydrogen production.
