The phase diagram and hardness of carbon nitrides [PDF]

open access: yesScientific Reports, 2015
AbstractNovel superhard materials, especially those with superior thermal and chemical stability, are needed to replace diamond. Carbon nitrides (C-N), which are likely to possess these characteristics and have even been expected to be harder than diamond, are excellent candidates.

Breaking through water-splitting bottlenecks over carbon nitride with fluorination

open access: yesNature Communications, 2022
Graphitic carbon nitride has long been considered a poor oxygen evolution catalyst. Here, the authors report a simple fluorination strategy to prevent the accumulation of inert C=O on carbon nitride to break through this bottleneck.
