Graphitic carbon nitride (g-CN) has been extensively investigated over the past decade for its potential utilizations in photocatalytic energy generation and pollutant degradation. To better meeting the requirements for practical utilizations, it is crucial to address the issue of poor charge separation properties in g-CN, which origin from the strong interactions in photogenerated electron-hole pairs. In this review, we summarized the pertinent studies on developing strategies to promote the charge separation properties of g-CN. The strategies can be categorized into two categories of promoting the surface migration of charge carriers and prolonging the lifetime of surface charge. Finally, we present potential challenges in promoting charge separation and offer feasible suggestions to face these challenges.
在过去十年中，石墨相氮化碳（g-CN）因其在光催化能量产生和污染物降解方面的潜在应用而受到广泛研究。为了更好地满足实际应用的需求，解决g-CN中电荷分离性能差的问题至关重要，这一问题源于光生电子-空穴对之间的强相互作用。在本综述中，我们总结了关于开发促进g-CN电荷分离性能策略的相关研究。这些策略可分为促进电荷载流子表面迁移和延长表面电荷寿命两类。最后，我们提出了促进电荷分离方面的潜在挑战，并提供了应对这些挑战的可行建议。
