The low quantum yield of photocatalytic hydrogen production in carbon nitride (CN) has been improved upon via the modulation of both the extrinsic and intrinsic properties of the material. Although the modification of extrinsic properties has been widely investigated in the past, recently there has been growing interest in the alteration of intrinsic properties. Refining the intrinsic properties of CN provides flexibility in controlling the charge transport and selectivity in photoredox reactions, and therefore makes available a pathway toward superior photocatalytic performance. An analysis of recent progress in tuning the intrinsic photophysical properties of CN facilitates an assessment of the goals, achievements, and gaps. This article is intended to serve this purpose. Therefore, selected techniques and mechanisms of the tuning of intrinsic properties of CN are critically discussed here. This article concludes with a recommendation of the issues that need to be considered for the further enhancement in the quantum efficiency of CN photocatalysts.
通过调节氮化碳（CN）材料的外在和内在性质，其光催化产氢的低量子产率已得到改善。尽管过去对外在性质的改性已得到广泛研究，但最近人们对内在性质的改变越来越感兴趣。优化CN的内在性质为控制光氧化还原反应中的电荷传输和选择性提供了灵活性，因此为实现卓越的光催化性能提供了一条途径。对调节CN内在光物理性质的最新进展进行分析，有助于评估目标、成果和差距。本文旨在实现这一目的。因此，本文将批判性地讨论用于调节CN内在性质的选定技术和机制。本文最后提出了一些建议，即进一步提高CN光催化剂量子效率需要考虑的问题。
