Switching Cathodic/Anodic Electrochemiluminescence of Ru(bpy)32+ Precisely via Homogeneous Nickel Nanoparticles Crystal Facets Sites Modulated ORR/OER
Mechanistic Illustration of the facet modulated Ru(bpy)32+ cathodic/anodic ECL system. O2 molecules undergo ORR at the cathode, while H2O molecules undergo OER at the anode on different catalyst facets. Ni/NG-1 exhibits high OER but low ORR activity, generating radicals that react with Ru(bpy)32+ to enhance cathodic ECL. In contrast, Ni/NG-2 shows high ORR but low OER activity, thus …
