Monolayer Growth Front of Precious Metals through Insulating Mesoporous Membranes

Monolayer Growth Front of Precious Metals through Insulating Mesoporous Membranes
Nicholas Linck, Alex Peek, Bruce J. Hinds
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.
