Photocatalytic Hydrogen Generation from a Visible-Light-Responsive Metal–Organic Framework System: Stability versus Activity of Molybdenum Sulfide Cocatalysts

Berend Smit, Andreas Züttel, Kyriakos Stylianou, Wen Luo, Daniele Ongari, Ngoc Tú Nguyên, Bardiya Valizadeh, Stavroula Kampouri, Ophélie Marie Planes

We report the use of two earth abundant molybdenum sulfide-based cocatalysts, Mo(3)S(13)(2-)clusters and 1T-MoS2 nanoparticles (NPs), in combination with the visible-light active metal-organic framework (MOF) MIL-125-NH2 for the photocatalytic generation o ...
