石墨氮化碳基材料由于其“地球丰富”的性质、结构的多功能性、可调节的电子和光学特性以及化学稳定性，已成为各种能源和环境应用的有前景的光催化剂。优化氮化碳的物理化学性质包括多种方法，包括固有结构缺陷的调节、形态控制、异质结构构建以及杂原子和金属原子掺杂。这些策略对于最终增强其光催化活性至关重要。先前的综述和大量实例主要集中在氮化碳基材料的合成、改性及其在光催化中的应用。然而，一直缺乏直接和深入的讨论来了解各种工程氮化碳的电子特性和功能以及它们的精确定制策略，并最终解释它们在目标光催化系统中改进性能的规律性和特异性。近十年来，我们课题组对氮化碳基材料及其在光催化中的应用进行了广泛的研究。这些研究证明了氮化碳材料的电子结构与其光催化反应性之间密切而复杂的关系。了解氮化碳的电子结构和功能以及不同的工程策略对于光催化过程从基础研究到实际应用的改进至关重要。

Electronic Structure and Functions of Carbon Nitride in Frontier Green Catalysis

Graphitic carbon nitride-based materials have emerged as promising photocatalysts for a variety of energy and environmental applications owing to their “earth-abundant” nature, structural versatility, tunable electronic and optical properties, and chemical stability. Optimizing carbon nitride’s physicochemical properties encompasses a variety of approaches, including the regulation of inherent structural defects, morphology control, heterostructure construction, and heteroatom and metal-atom doping. These strategies are pivotal in ultimately enhancing their photocatalytic activities. Previous reviews with extensive examples have mainly focused on the synthesis, modification, and application of carbon nitride-based materials in photocatalysis. However, there has been a lack of straightforward and in-depth discussion to understand the electronic characteristics and functions of various engineered carbon nitrides as well as their precise tailoring strategies and ultimately to explain the regularity and specificity of their improved performance in targeted photocatalytic systems. In the past ten years, our group has conducted extensive investigations on carbon nitride-based materials and their application in photocatalysis. These studies demonstrate the close yet intricate relationship between the electronic structure of carbon nitride materials and their photocatalytic reactivity. Understanding the electronic structure and functions of carbon nitride, as well as different engineering strategies, is essential for the improvement of photocatalytic processes from fundamental study to practical applications.
