Optimized hot electron injection from Cu nanoparticles to S-doped C₃N₄by the formed S–Cu bonds for an enhanced photocatalytic performance

Abstract

Low-cost and high-abundance Cu nanostructures are the potential near-infrared (NIR) surface plasmonic resonance (SPR) photosensitizer for carbon nitride (C3N4) photocatalysts, but their low activity and stability need to be improved....

Enhanced plasmonic photocatalytic performance of C3N4/Cu by the introduction of a reduced graphene oxide interlayer

“…30 For example, our previous work showed that the S-Cu bonds between sulfur doped C 3 N 4 and Cu NPs can effectively improve the hot electron transport efficiency. 31 In this paper, the formed C-O-C and C-O-Cu bonds between the RGO buffer layer and CN and Cu NPs can effectively extract photogenerated electrons from CN and hot electrons from Cu. In addition, the light utilization range of the CN photocatalyst can be extended to the near-infrared region by the introduction of Cu NPs.…”
