Abstract:
The photocatalytic splitting of water into H2 and O2 has attracted considerable attention because the process presents an avenue for direct generation of an energy carrier that is easily stored andtransformed into electric energy. [1] In this paper different silver salts were deposited on a conducting support of TiO2/ FTO electrodes through the deposition-precipitation method and have been used as visible light induced photoanode in water splitting reaction. PhotoElectrochemical measurements such asCurrent-Voltage and Chronoamperometry diagrams demonstrated that the Silver salts loading enhanced the visible spectral absorption of TiO2 and consequently a higher O2 and H2 production, were observed.Via some characterization techniques such as XRD, EDX and SEM, it is obvious that the thinlayer of silver salts are nanostructured materials. Plus, it is obvious that the light sensitivity in the visible part of the spectrum for the prepared photoanodes is due to self-sensitization caused byreduced silver species. [2]
