<br/><br/> This work has been carried out to investigate the electrocatalytic oxidation of methanol at nickel and titanium silicaliteelectrodes , pre - soaked in metal ions solutions , in alkaline mediumThree catalyst ions were examined ; namely : nickel , cobalt and rutheniumThe methanol oxidation reaction was mainly governed by the presence of certain active oxide species as electron transfer mediators
