«The direct growth of anchored MoSoy nanocrystals on
graphene sheets may enhance the formation of strongly coupled hybrid materials with intimate, seamless electron transfer pathways, thus accelerating the electron transfer rate
for the chemical desorption of hydrogen from the
catalyst, further reducing the energy required
for the reaction to take place,» Sasaki said.

catalyst foil, and we find that some of the common models employed to explain 3D crystal growth just do not work
for this material.
