✦ Synopsis
The electrodeposition of oxygenated rhenium species from ReO, acid solutions on polycrystalline Pt electrodes has been investigated. Results suggest that ReO, at sub-monolayer levels is probably involved as adsorbed species. Electrocatalytic effects observed in HCOOH electrooxidation can be interpreted on the basis that ReO, may act as a third-body catalyst, preventing or eliminating the strongly bound intermediates that poison the electrode, as well as a bi-functional catalyst facilitating the existence of oxygen-containing species such as OH radicals formed during its oxidation to ReO,
