摘要
MnO2 nano-materials can remarkably catalyze the electrochemical reduction reaction of O-2, so MnO2 nano-materials can be used as catalysts for electrogenerated chemiluminescence (ECL) of Ru(bpy)(3)(2+) in this paper. As a result, a novel cathodic ECL of Ru(bpy)32 at positive potential of +O.4 V (vs. Ag/AgCl) was triggered by reactive oxygen species (HO2 center dot- or OH center dot-) on an in situ electrodeposited MnO2 nano-structured electrode. Finally, catalytic mechanism of MnO2 nano-materials is deduced and provides a theoretical basis for preparing novel ECL Sensor with high sensitivity.
