在提高石墨氮化碳（g-CN）的可见光催化裂解水活性的过程中，发现了其多种有利的性能。这些特性使g-CN能够作为具有多种输出模式的传感信号传感器工作。本文综述了近年来定制g-CN纳米结构在传感领域的最新应用。首先，g-CN纳米结构具有大表面积、丰富的活性位点和在水中的高分散性以及它们的制备方法。然后，按照固定识别元素的顺序描述了这些g-CN纳米结构的传感应用；半导体和电子给体特性衍生出信号转导模式，以及改善传感性能的有效途径。最后，对该研究领域面临的挑战和未来的可能性进行了总结和展望。
Various beneficial properties of graphitic carbon nitride (g-CN) have been discovered during the promotion of its visible-light-driven photocatalytic activity for water splitting. These properties enable g-CN working as a sensing signal transducer with multiple output modes. In this review, state-of-the-art sensing applications of tailored g-CN nanostructures in the recent years are presented. Initially, g-CN nanoarchitectures featuring large surface areas, abundance of active sites, and high dispersity in water are presented along with their preparation methods. Then, sensing applications of these g-CN nanoarchitectures are described in sequence of the immobilization of recognition elements; semiconductor and electron donating properties derive signaling transduction modes, and efficient approaches for improving sensing performances. The review is concluded with a summary and some perspectives on the challenges and future possibilities of this research field.
