In this paper, the anodic electrogenerated chemiluminescence (ECL) behavior of graphite-like carbon nitride (g-C₃N₄) is studied using cyclic voltammetry with triethanolamine (TEA) as a coreactant. The possible anodic ECL response mechanism of the g-C₃N₄/TEA system is proposed. Furthermore, it is observed that the anodic ECL signal can be quenched efficiently in the presence of rutin, on the basis of which a facile anodic ECL senor for the determination of rutin is developed. This ECL sensor is found to have a linear response in the range of 0.20鈥?5.0 渭M and a low detection limit of 0.14 渭M (at signal-to-noise of 3). These results suggest that semiconductor g-C₃N₄ has great potential in extending the application in the ECL field as an efficient luminophore.
