摘要: Abstract The reactions involved in the electroreduction and electroformation of O2 on electrodes prepared by precipitation nickel hydroxide different conducting substrates (platinum or vitreous carbon) alkaline solutions are investigated. catalytic activity these for evolution reaction is independent nature substrate but depends ageing conditions hydroxide. mechanisms explained through participation both Ni(III) very reactive Ni(IV) species. electrocatalytic related to u-NiOOH occurs surface mainly determined characteristic substrate.
