Photocatalysis is attracting increased attention in solving the energy crisis and environmental pollution. Graphitic carbon nitride (g-C3N4), a non-metal photocatalyst, has been regarded as an ideal photocatalyst to solve these problems because of its chemical stability and unique optical properties. However, traditional g-C3N4 exhibits moderate photocatalytic activity due to its low specific surface area and fast recombination rate of photogenerated electrons. Among the many modified g-C3N4 materials, porous carbon nitride (PCN) can solve the shortcomings of traditional g-C3N4 because of PCN's increased number of surface-active sites, specific surface area, light harvesting, diffusion and adsorption/activation. However, a frontier, comprehensive summary of the development of PCN is less reported. Thus, a review on recent developments in PCN research is urgently needed to further promote its advancement. In this review, the synthesis methods, structures and properties and photocatalytic applications of PCN photocatalysts are described in detail. The current challenges and future development of PCN/PCN-based photocatalysts are discussed. This review may present an up-to-date view of the PCN development to provide an in-depth understanding of PCN-based photocatalysts.

用于太阳能光催化的多孔石墨氮化碳。

在解决能源危机和环境污染方面,光催化正受到越来越多的关注。非金属光催化剂石墨碳氮化物(g-C3N4)由于其化学稳定性和独特的光学性能而被视为解决这些问题的理想光催化剂。然而,传统的g-C3N4由于其低的比表面积和光生电子的快速重组速率而表现出中等的光催化活性。在许多改性的g-C3N4材料中,多孔氮化碳(PCN)可以解决传统g-C3N4的缺点,因为PCN的表面活性位点数量,比表面积,光收集,扩散和吸附/活化数量增加。但是,关于PCN发展的前沿,全面的摘要报道较少。从而,迫切需要对PCN研究的最新发展进行回顾,以进一步促进其发展。在这篇综述中,详细描述了PCN光催化剂的合成方法,结构和性能以及光催化应用。讨论了基于PCN / PCN的光催化剂的当前挑战和未来发展。这篇评论可能会提供有关PCN开发的最新视图,以提供对基于PCN的光催化剂的深入了解。
