The photosensitizer is one of the important components in the photocatalytic system. Molecular photosensitizers have well-defined structures, which is beneficial in revealing the catalysis mechanism and helpful for further structural design and performance optimization. However, separation and recycling of the molecular photosensitizers is a great problem. Loading them into/on two/three-dimensional supports through covalent bonds, electrostatic interactions, and supramolecular interactions is a method that enhances their separation and recycling capability. Nonetheless, the structures of the resulting composites are unclear. Thus, the development of highly crystalline heterogeneity methods for molecular photosensitizers, albeit greatly challenging, is meaningful and desirable in photocatalysis, through which heterogeneous photosensitizers with well-defined structures, definite catalysis mechanisms, and good catalytic performance would be expected.
光敏剂是光催化系统中的重要组成部分之一。分子光敏剂具有明确定义的结构,这有助于揭示催化机理并有助于进一步的结构设计和性能优化。然而,分离和回收分子光敏剂是一个很大的问题。通过共价键、静电相互作用和超分子相互作用将它们加载到二/三维支撑体中是一种增强其分离和回收能力的方法。然而,所得复合材料的结构尚不清楚。因此,在光催化中,开发高度晶化的分子光敏剂异质性方法虽然极具挑战性,但具有意义和可取之处,通过这种方法,可以期望得到具有明确定义的结构、明确的催化机理和良好催化性能的异质光敏剂。
