摘要: Abstract Nanocollision electrochemistry is employed to evaluate the ORR's activity of one single Pt nanoparticle, effect size and ligand investigated. The size-normalized nanoparticle 4 nm two times higher than that 25 nm, confirming intrinsic does depend on nanoparticles. It further found adsorbed yield electrocatalysis, adsorption strength follows order PVP > CTAB citrate. This work significance understand nature electrocatalysis at level an individual entity, which makes structure-activity correlation in a more reliable way.
