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+.
