Photoelectrochemical conversion by SnP-C/Fe/PAni: An integrated chemical system

The composite SnP-C/Fe/PAni was obtained as a powder by polymerization of aniline in the interlayer space of the host tin (IV) 2-carboxyethylphosphonate (SnP-C). The photoelectrochemical behavior of the composite was investigated as a function of applied potential, polyaniline concentration and direction of the polychromatic irradiation. The stability of the device using a liquid electrolyte was also determined. The photoelectrochemical response is sensitive to the oxidation state of the polymer. Depending on the potential applied to the electrode we observe cathodic or anodic photocurrents.
