The chemical protonation of graphitic carbon nitride (CN) solids with strong oxidizing acids, for example HNO3, is demonstrated as an efficient pathway for the sol processing of a stable CN colloidal suspension, which can be translated into thin films by dip/disperse-coating techniques. The unique features of CN colloids, such as the polymeric matrix and the reversible hydrogen bonding, result in the thin-film electrodes derived from the sol solution exhibiting a high mechanical stability with improved conductivity for charge transport, and thus show a remarkably enhanced photo-electrochemical performance. The polymer system can in principle be broadly tuned by hybridization with desired functionalities, thus paving the way for the application of CN for specific tasks, as exemplified here by coupling with carbon nanotubes.
石墨相氮化碳（CN）固体与强氧化性酸（例如 HNO3）的化学质子化作用被证明是一种有效的途径，可以将其用于稳定的 CN 胶体悬浮液的溶胶处理，该胶体悬浮液可以通过浸涂/分散涂覆技术转化为薄膜。CN 胶体的独特性质，如聚合基质和可逆氢键，导致源自溶胶溶液的薄膜电极具有高机械稳定性和改进的电荷传输导电性，从而表现出显著增强的光电化学性能。该聚合物体系原则上可以通过与所需官能团的杂化进行广泛调节，从而为 CN 在特定任务中的应用铺平道路，这里通过与碳纳米管耦合为例进行了说明。
