Structural and Electronic Study of an Amorphous MoS₃ Hydrogen‐Generation Catalyst on a Quantum‐Controlled Photosensitizer

Light–water reactor: An amorphous molybdenum sulfide species structurally similar to reduced MoS3 is shown to be photocatalytically active for hydrogen generation from H2O with visible light (see picture; TEOA=triethanolamine). Thermally deposited in one step, MoS3 is photosensitized by quantum-controlled semiconductor nanocrystals that serve as model systems for the photophysics of solar fuel generation.
