Formation, characterization and electrocatalytic activity of layer-by-layer self-assembled films containing polyoxomolybdate over Au surfaces

We describe a novel strategy for the controlled fabrication of well-defined multilayer films incorporating a polyoxomolybdate anion (PMo12O403-, POM) via ion exchange on Au electrodes. Composite films were thoroughly characterized by ellipsometry, X-ray photoelectron spectroscopy (XPS), FTIR-ATR, qu...
