Mechanism studies of hydrazine electro-oxidation by a platinum ultramicroelectrode: Effects of supporting electrolytes

10.1016/j.jelechem.2018.04.012

2018-04-04

The effects of the supporting electrolyte on electro-catalytic reaction of hydrazine hydrate (HH) were studied by a platinum ultramicroelectrode. We found that the H+ electric field generated during the catalytic process can partly hinder the reactants from p...

Conditions for a nearly perfect match between pulse voltammetry and linear scan voltammetry
