There are different types of materials comprising of carbon and nitrogen elements. Typical materials are the cyanogen family, beta carbon nitride, graphitic carbon nitride, azafullerenes, and heterofullerenes, N-containing heterocycles. Except cyanogen (C₂N₂) is a gas, most others are solid. Among these solids, the graphitic carbon nitride, with the general chemical formula of C₃N₄, is widely studied in heterogeneous catalysis and energy storage. Such applications exploit the resiliency of the material in different environments due to its labile protons and Lewis acid functionalities, as well as its layered structure. The structure of graphitic C₃N₄ allows it to store a significant amount of hydrogen. Furthermore, it offers the space for dopants, which are used purposely for tuning the band gap and the electronic properties of C₃N₄ to make it suitable for water splitting using sun light, or many other applications in waste water treatment under radiation. We think that the material is important and it is not being exploited at its highest capability, especially in hydrogen production via water splitting technique. This review aims to summarize recent outcomes using the carbon nitride material in hydrogen production, and a brief about hydrogen storage. We also highlight future research directions which might worth being persuaded.

有不同类型的材料，包括碳元素和氮元素。典型的材料是氰家族，β氮化碳，石墨碳，氮化azafullerenes，和heterofullerenes，Ñ含杂环。除了氰 (C ₂ N ₂ ) 是气体外，其他大部分都是固体。在这些固体中，具有化学通式C ₃ N ₄的石墨氮化碳在多相催化和储能方面得到了广泛的研究。由于其不稳定的质子和路易斯酸官能团以及其分层结构，此类应用利用了材料在不同环境中的弹性。石墨C ₃ N ₄的结构允许它储存大量的氢气。此外，它还为掺杂剂提供了空间，这些掺杂剂专门用于调整 C ₃ N ₄的带隙和电子特性，使其适用于利用太阳光分解水，或在辐射下的废水处理中的许多其他应用。我们认为这种材料很重要，但并未以最高能力开发，尤其是在通过水分解技术生产氢气方面。本综述旨在总结使用氮化碳材料制氢的最新成果，并简要介绍储氢。我们还强调了可能值得说服的未来研究方向。
