Polymeric carbon nitrides (CN) as star semiconductive materials have attracted increasing attention owing to its numerous superior features, such as facile synthesis, non-toxicity, earth-abundant, high physicochemical stability, and all of these endow its great potentials from photocatalysis to environmental remediation, sensing, biomedicine, and other emerging fields. The facile synthesis and polymeric characteristic of CN allow easy tailoring of their framework from elements, the structure of monomers, and tectonic units to control their properties and then to obtain superior performance in various applications. Although there have been reviews summarizing design and modification strategies of CN-based materials, most of them have focused only on surface engineering and nanostructure construction, lacking analysis from the point of view of the framework structure. This review systematically summarized the inspiring breakthroughs on rational design and fabrication of the CN framework from elements to monomers, and then to tectonic units via various strategies including elemental doping, defects engineering, tuning the crystalline degree, coordination engineering and molecular doping. Importantly, we summarized general rules between CN framework structure and their performance in various applications to better understand the current state-of-the-art status and plans for future research directions.

聚合碳氮化物的骨架结构工程及其最新应用

聚合物氮化碳(CN)作为星型半导体材料,由于其合成容易、无毒、地球储量丰富、物理化学稳定性高等众多优点而受到越来越多的关注,所有这些都赋予了它从光催化到环境的巨大潜力。修复、传感、生物医学等新兴领域。CN 的简便合成和聚合特性允许从元素、单体结构和构造单元轻松定制其框架,以控制其性能,然后在各种应用中获得优异的性能。尽管已有综述总结了基于 CN 的材料的设计和改性策略,但其中大多数只关注表面工程和纳米结构构建,缺乏从框架结构的角度分析。本综述系统地总结了通过元素掺杂、缺陷工程、调整结晶度、配位工程和分子掺杂等多种策略在从元素到单体再到构造单元的合理设计和制造 CN 框架方面取得的鼓舞人心的突破。重要的是,我们总结了 CN 框架结构及其在各种应用中的性能之间的一般规则,以更好地了解当前的最新状态和未来研究方向的计划。缺陷工程,调整结晶度,配位工程和分子掺杂。重要的是,我们总结了 CN 框架结构及其在各种应用中的性能之间的一般规则,以更好地了解当前的最新状态和未来研究方向的计划。缺陷工程,调整结晶度,配位工程和分子掺杂。重要的是,我们总结了 CN 框架结构及其在各种应用中的性能之间的一般规则,以更好地了解当前的最新状态和未来研究方向的计划。
