The presence of amine functional groups allows for the uniform dispersion of CdSe–DETA on PCN by acting as an organic linker to anchor CdSe–DETA onto PCN nanosheets and forming a close-contact interface.
Here, amine-modified step-scheme (S-scheme) porous graphite carbon nitride (g-C 3N 4)/CdSe–diethylenetriamine (A-PCN/CdSe–DETA) was fabricated via a simple one-step microwave hydrothermal method. However, rapid recombination of photoexcited charges in semiconductors often gets in the way of photocatalytic reaction and annoyingly suppresses the photocatalytic performance. Photocatalytic CO 2 reduction has been known to be one of the most potential technologies for sustaining the development of human society.
