摘要:

特殊形貌石墨相氮化碳(g-C3N4)基材料具有多级结构、可调变的短程电子传递路径等特点,能较好地解决传统g-C3N4基材料存在的比表面积小、可见光利用效率低以及光生载流子易复合等问题,因而具有广阔的发展前景和应用潜力。本文对管/棒/阵列、多孔微球、凝胶和仿生形貌等特殊形貌g-C3N4基光催化材料的研究进展进行了系统评述,并对该类材料的形貌与催化功能之间的构效关系进行了分析和总结。指出目前该类材料的研究尚处于起步阶段,还存在着形貌数量种类偏少、合成方法较少、构效关系认识不够深入等问题。因此,该领域未来应该在拓展形貌种类、调控能带位置、光生载流子转移机理和分子模拟等方面进行深入研究,为高性能光催化剂的研制提供更好的思路。

Abstract:

The g-C3N4-based materials with special morphologies have the characteristics of hierarchical structure and adjustable short-range electron transfer pathway etc., and thus could well overcome the problems of traditional g-C3N4-based materials such as small specific surface area, low visible-light utilization efficiency, and high recombination rate of photo-generated carriers. Consequently, they demonstrate broad development prospect and great application potential in the photocatalysis field. This review highlights the recent advances of g-C3N4-based materials with special morphologies, such as tube/rod/array, porous microsphere, gel and biomimetic morphology, and discusses the structure-function relationship between their morphologies and the photocatalytic performance. At present, the research for this kind of materials is in their infancy and they still exhibit a few problems, such as limited morphology types, few synthetic methods and insufficient understanding of the structure-function relationship. Therefore, the investigation should be focused on the expansion of the morphology type, regulation of the energy band position, the transfer mechanism of photo-generated carriers and the molecular modeling in the future, so as to afford better ideas for the exploration of high-performance photocatalytic materials.
