Photoelectrochemical (PEC) detection technology shows great potential in alleviating the increasingly serious environmental pollution problem. The satisfactory PEC performance mainly depends on the photoelectric conversion efficiency of photoelectrode material. Graphitic carbon nitride (g-C3N4) has made great progress in the field of photocatalysis due to its strong light response. Interestingly, g-C3N4 has also attracted many interests in PEC sensing for its capability and unique superiorities, but relevant reviews are yet to be reported. This review mainly describes recent advances in the PEC sensing application of g-C3N4-based photoactive materials. The strategies for the improvement of optoelectrical conversion efficiency of g-C3N4 materials and their multifunctional applications for the PEC detection of environmental pollutants are summarized. The corresponding PEC sensing mechanism is introduced, namely, the correlative enhancement mechanism of light absorption and the separation and migration of photoexcited charge. Finally, the challenges and opportunities for the development of g-C3N4-based PEC sensors are prospected.

用于环境污染物光电化学检测的石墨氮化碳
光电化学（PEC）检测技术在缓解日益严重的环境污染问题方面显示出巨大潜力。令人满意的PEC性能主要取决于光电极材料的光电转换效率。石墨氮化碳（gC 3 N 4）由于其强光响应在光催化领域取得了长足的进步。有趣的是，gC 3 N 4也因其能力和独特的优势而引起了PEC传感的许多兴趣，但相关评论尚未报道。这篇综述主要介绍了gC 3 N 4在PEC传感应用中的最新进展基光敏材料。总结了提高gC 3 N 4材料光电转换效率的策略及其在PEC检测环境污染物中的多功能应用。介绍了相应的PEC传感机制，即光吸收的相关增强机制与光激发电荷的分离和迁移。最后，展望了基于gC 3 N 4的PEC传感器发展面临的挑战和机遇。
