Abstract

Molecularly grafted carbon nitride (CN) nanosheets, matching well with the emission energy of upconversion phosphors (UCPs), were acquired for the first time. As a result of energy gap engineering, the assembled composites successfully realized the full use of visible-NIR light and afforded much higher activity than any CN- or UCP-based photocatalyst ever reported.
