Abstract
Gold nanoparticles (AuNPs) decorated carbon nitride nanosheets (Au-g-C3N4 NSs) could work as an excellent on-electrode cathodic coreactant for Ru(bpy)32+. Based on the regulation effect of AuNPs and mercury (Hg2+) for the dual-potential electrochemiluminescence (ECL) of Ru(bpy)32+, a simple, sensitive and selective ECL system was created for the ratiometric sensing of Hg2+.
摘要
金纳米粒子（AuNPs）修饰的碳氮纳米片（Au-g-C3N4 NSs）可用作 Ru(bpy)32+的优秀电极上阴极共反应物。基于 AuNPs 和汞（Hg2+）对 Ru(bpy)32+的双电位电化学发光（ECL）的调节作用，建立了一个简单、灵敏和选择性的 ECL 体系，用于 Hg2+的比率感应。
