Tunable Pt-NiO interaction-induced efficient electrocatalytic water oxidation and methanol oxidation.

For instance, Pt single atoms loaded on thiolated multiwalled carbon nanotubes are barely significant to the MOR catalytic activity, while Pt clusters possess a small MOR overpotential, 28 attributed to the requirement of at least three Pt atoms to form a combined active site for the MOR. 29 The dispersion and size of Pt are vital factors in determining the metal–support interactions and thus optimizing the electrocatalytic activity.
