A new type of carbon nitride-based polymer composite for enhanced photocatalytic hydrogen production

A new type of graphitic C3N4-based composite photocatalysts was designed and prepared by co-loading PEDOT as a hole transport pathway and Pt as an electron trap on C3N4. The as-prepared C3N4–PEDOT–Pt composites showed drastically enhanced activity for visible light-driven photocatalytic H2 production compared to those of C3N4–PEDOT and C3N4–Pt, possibly due to the spatial separation of the reduction and oxidation reaction sites.
