Electroless Deposition of Palladium Nanoparticles on Graphdiyne Boosts Electrochemiluminescence
Renmin University of China · Beijing Normal University
Abstract
Modulating the electronic structure of metal nanoparticles via metal–support interaction has attracted intense interest in the field of catalytic science. However, the roles of supporting substrates in regulating the catalytic properties of electrochemiluminescence (ECL) remain elusive. Here, we find that the use of graphdiyne (GDY) as the substrate for electroless deposition of Pd nanoparticles (Pd/GDY) produces the most pronounced anodic signal enhancement in luminol–dissolved oxygen (O2) ECL system as co-reactant accelerator over other carbon-based Pd composite nanomaterials. Pd/GDY exhibits electrocatalytic activity for the reduction of O2 through a four-electron pathway at approximately −0.059 V (vs…
