Abstract: Electrocatalytic water oxidation occurs at fluoride-doped tin oxide (FTO) electrodes that have been surface-modified by addition of Co(II). On the basis of X-ray photoelectron spectroscopy and transmission electron microscopy measurements, the active surface site appears to be a single site or small-molecule assembly bound as Co(II), with no evidence for cobalt oxide film or cluster formation. On the basis of cyclic voltammetry measurements, surface-bound Co(II) undergoes a pH-dependent 1e(-)/1H(+) oxidation t… Show more

“…Kent et al used fluoride-doped tin oxide (FTO) as support loading a single site or small-molecule assembly bounded Co (II). [76] On the basis of cyclic voltammetry measurements, surface-bound Co(II) undergoes a pH-dependent oxidation to Co(III), which is followed by pH-dependent catalytic water oxidation. Controlled-potential electrolysis at 1.61 V RHE at pH 7.2 resulted in sustained water oxidation catalysis at a current density of 0.16 mA/cm 2 .…”

“…The ultimate aim is the complete mineralization of the organic pollutants. The most known electrodes are based on titanium oxides Ti n O 2n−1 (n from 4 to 10), indium‐doped tin oxide (ITO), and fluorine‐doped tin oxide (FTO) . However, these present some important limitations.…”

“…Especially, fluorine (F) has been considered as one of the most effective dopants for enhancing light absorption. Fluorine-doped tin oxide (FTO) is widely used as conducting electrodes for photoelectrochemical reactions [13]. However, owing to the rapid recombination that photoinduction carries, the photocatalytic activity of fluorine-doped tin oxide (FTO) for H 2 evolution is usually very low, or non-existent, in the presence of a sacrificial agent [14].…”
