尽管在过去的几十年里已经开发了大量的光催化方法来克服主要的缺点，例如；宽频带隙和电荷载流子的快速体积/表面重组，在进行基于系统物理化学性质的实验之前，研究人员还需要进行仔细的系统研究。因此，在这篇综述中，详细讨论了控制所产生的带电载流子的迁移和电荷分离的带边位置及其对光催化系统的影响。条带边缘位置的知识是合理设计高效光催化系统的关键先决条件。增强机制必须符合这些标准，才能在多相光催化科学领域中可靠。
Although, plenty of photocatalytic approaches have been developed in the past few decades to overcome major drawbacks, such as; wide band gap and fast volume/surface recombination of the charge carriers, the researchers still need to carry out careful systematic studies before conducting experiments based on physicochemical properties of a system. Thus, in this review, a detailed discussion of the band edge positions controlling the migration and charge separation of the produced charged carriers and its impact onto the photocatalytic systems are provided. The knowledge of band edge positions is a crucial prerequisite to a rational design of an efficient photocatalytic system. The enhancement mechanism should match these criteria to be reliable in the field of heterogeneous photocatalysis science.
