In this study, three-dimensional gold-nickel-molybdenum (Au(NiMo)) catalysts have been studied as for the oxygen evolution reaction (OER). The deposited on a titanium surface using electroplating and galvanic displacement techniques. modification of NiMo with low amount Au crystallites in range 1.2– 5.2 μgAucm–2 results enhanced activity OER alkaline medium compared to respective binary un-modi...
