A graphene dispersed CdS-MoS2 nanocrystal ensemble for cooperative photocatalytic hydrogen production from water.

ABSTRACT

We report a simple but highly cooperative ensemble with CdS and MoS2 nanocrystals dispersed on graphene sheets it is demonstrated that CdS nanocrystals can capture light energy and facilitate excited electron transfer to MoS2 for catalytic hydrogen production via the 2-D graphene which plays a key role as an efficient electron mediator.
