Breaking through water-splitting bottlenecks over carbon nitride with fluorination
Nature 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.
