NHS-Enabled Molecular Stitching of g-C3N4/Graphitic-Carbon In-Plane Heterojunctions Activates n→π* Transitions for Efficient Visible-Light Photocatalytic Hydrogen Production.
An NHS-assisted molecular self-assembly ("molecular stitching") route is presented for constructing g-C3N4/graphitic-carbon (g-C3N4/Cg) in-plane heterojunction nanosheets with tunable n→π* transitions. Using N-hydroxysuccinimide and melamine as precursors, covalent coupling to a conductive sp2-carbon network perturbs h...
