The electrochemical reduction of carbon dioxide (CO2) has been studied on various metal electrodes including main group and transition elements in aqueous solution. Of these electrodes, silver and gold are found to have catalytic activity for the conversion of CO2 to CO with considerably high Faradaic efficiencies. However, no work has been done to evaluate the electrocatalytical property of these two electrodes in the same electrochemical system under the same condition. In present work, we investicate the electrocatalytical property of Ag and Au electrodes in the same electrolysis cell and under the same condition. We found Au electrode exhibits higher current density and higher faradaic efficiency for CO formation than Ag electrode.

<p>A manganese substituted Anderson type polyoxometalate, [MnMo<sub>6</sub>O<sub>24</sub>]<sup>9-</sup>, tethered with an anthracene photosensitizer was prepared and used as catalyst for CO<sub>2</sub> reduction. The polyoxometalate-photosensitizer hybrid complex, obtained by covalent attachment of the sensitizer to only one face of the planar polyoxometalate, was characterized by NMR, IR and mass spectroscopy. Cyclic voltammetry measurements show a catalytic response for the reduction of carbon dioxide, thereby suggesting catalysis at the manganese site on the open face of the polyoxometalate. Controlled potentiometric electrolysis showed the reduction of CO<sub>2</sub> to CO with a TOF of ~15 sec<sup>-1</sup>. Further photochemical reactions showed that the polyoxometalate-anthracene hybrid complex was active for the reduction of CO<sub>2</sub> to yield formic acid and/or CO in varying amounts dependent on the reducing agent used. Control experiments showed that the attachment of the photosensitizer to [MnMo<sub>6</sub>O<sub>24</sub>]<sup>9-</sup> is necessary for photocatalysis.</p><div><br></div>
