In order to study the sensitization mechanism of chlorophyll, ethanol extract of spinach chlorophyll served as sensitizers of TiO₂ nanotubes electrodes, and the aqueous solution of Na₂SO₄ was used as electrolyte to measure the photocurrent activity of the as-obtained electrodes. Photocurrent response results show that the TiO₂ nanotubes electrode changes its photocurrent value after sensitizing, while the pristine Ti electrode has weak photocurrent response. Cyclic voltammetry curves indicate that the oxidation of sensitized TiO₂ electrodes is more reactive than unsensitized ones. The incident photocurrent conversion efficiency(IPCE) of TiO₂ electrodes sensitized by extracts from different chlorophyll concentrations was tested. The result shows that, at optimized concentration(7.123~71.23 μg/L), sensitizers can increase the IPCE value of electrodes over 2 times than that before sensitizing, while at high concentration(7123 μg/L), the IPCE value decreases obviously. It is found that the characteristic peak positions of the IPCE spectra change very little between sensitized and unsensitized electrodes. The absorption spectrum of spinach pigment and the sensitization efficiency(SE_λ) spectra reveal the mechanism of the enhancement of photoelectric activity as chlorophyll molecules react with photo-generated hole of TiO₂ and reduce the rate of electron-hole recombination, resulting in an increased IPCE value of TiO₂ nanotube electrodes.
