Photo Electrode

A heterogeneous structured photo electrode using CDS -modified TiO2nanotube arrays (TNA) was fabricated. The CDS nano particles were precipitated by immersing TNA into NaS and Cd (ClO4)2solution, where the number of immersion gave different amount of CDS precipitates. The effect of CDS on the performance of photochemical cell of TNA was evaluated. FESEM, EDS, XRD and UV-Visible were employed to characterize the structures and properties of CDS -modified TNA heterogeneous structure. The water splitting experiments were carried out using these CDS -modified TNA under standard AM 1.5 solar illumination (100mW/cm2>). An optimum hydrogen generation rate of 20.61μmole/cm2>)h (~0.50 ml/cm2>)h) was obtained. It was considered that the smaller band gap of CDS rendered the electrons a rapid transportation to the TiO2nanotube arrays and the recombination of electron-hole was therefore effectively prevented. In summary, the CDS nano particles were effective in promoting the catalytic effect of TNA for hydrogen production.
