Highly dispersed Ag nanoparticles in situ creating rich cyano defects in carbon nitride for efficient photocatalytic H2 production

Uniform Ag nanoparticles, rich cyano defects, and conjugated carbon dopants were simultaneously implanted into the carbon nitride framework by a one-step thermal polycondensation method. The abundant cyano defects act as charge transfer channels to promote the photoinduced electron transfer, thus significantly improving the photocatalytic H2 evolution activity.
