“…There have been a number of studies of Pt-Ru codeposits on various substrates, i. e, on glassy carbon [22][23][24][25], gold [33][34][35], and platinum [8,[13][14][15][16][17][18][19][20]36]. They have been directed toward the catalytic characterization of these alloys, accompanied by relevant information on their composition, morphology and structure [11,[17][18][19][20]24,26,37,38].…”
