title: Bipolar Carrier Transfer Channels in Epitaxial Graphene/SiC Core-Shell Heterojunction for Efficient Photocatalytic Hydrogen Evolution.
abstract: Bipolar carrier transfer channels exist in the in situ epitaxial-graphene-wrapped 6H-SiC core-shell heterojunction due to the self-doping of graphene. Due to the special interface structure and high graphene quality, this material exhibits significant photocatalytic enhancement. Its hydrogen evolution efficiency is greater than that of the Pt/SiC composite. This micrometer-sized metal-free photocatalyst exhibits an activity comparable to that of metal-based nanophotocatalysts.
