Abstract

Nanocomposites based on molybdenum disulfide (MoS2) and different carbon modifications are intensively investigated in several areas of applications due to their intriguing optical and electrical properties. Addition of a third element may enhance the functionality and application areas of such nanocomposites. Herein, we present a facile synthetic approach based on directed thermal decomposition of (Ph4P)(2)MoS4 generating MoS2 nanocomposites containing carbon and phosphorous. Decomposition at 250 degrees C yields a composite material with significantly enlarged MoS2 interlayer distances caused by in situ formation of Ph3PS bonded to the MoS2 slabs through MoS bonds and (Ph4P)(2)S molecules in the van der Waals gap, as was evidenced by P-31 solid-state NMR spectroscopy. Visible-light-driven hydrogen generation demonstrates a high catalytic performance of the materials.
