Abstract:
Monolayers of precious metals are deposited within the pores of insulating mesoporous anodized aluminum oxide (AAO) membranes via a new electrochemical underpotential Cu deposition growth front mechanism, followed by spontaneous galvanic replacement of copper by platinum or iridium as demonstrated by XPS, ICP-OES, conductivity, and current analysis. Applications include fuel cells, hydrogen storage, flow batteries, and electrocatalytic conversions.
