Enhancing Hydrogen Evolution Activity of Monolayer Molybdenum Disulfide via a Molecular Proton Mediator

Xiangye Liu et al.

Summary: The study demonstrates that the hydrogen evolution reaction (HER) activity of monolayer MoS2 electrocatalysts can be significantly enhanced by modulating active sites through the introduction of a molecular mediator. Sodium dodecyl sulfate (SDS) is shown to promote the intrinsic HER activity of both terrace-based sulfur vacancies (VS) and edge sites, leading to up to 5 orders of magnitude increase in turnover frequency (TOF) for both sites. Simulations suggest that SDS facilitates proton adsorption by catching protons from hydronium ions and releasing them to VS, thereby reducing the energy barrier and creating a stair-case-like free energy profile.

Summary: The decoupled amphoteric water electrolysis system, assisted with MnO2/Mn2+ redox mediator, separates the tightly coupled hydrogen and oxygen production processes into two independent processes, allowing high-efficiency hydrogen production under high power input. This system can be integrated with an Mn-Zn battery to achieve flexible conversion from renewables to hydrogen and electric energy, making full use of renewable resources.
