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

Abstract

In the obtained Ag–C–CN photocatalyst, the cyano defects act as charge transfer channels to promote electron transfer, making Ag nanoparticles more active as a HER cocatalyst.

Partially cross-linked carbon nitride with unimpeded charge transfer between different chains for boosting photocatalytic hydrogen production

“…In addition, PC-CN and PTI both exhibit a new peak at 2170 cm À1 ascribed to cyano groups. 26,27 The generation of cyano groups is owing to the decomposition of the condensation intermediates induced by molten salts. More cyano groups are introduced into the obtained PC-CN sample than PTI, most likely due to the faster corrosion in solid molten salts.…”
