Photoanode of Photoelectrochemical Biofuel Cell Sensitized by Magnesium Tetraphenylporphyrin

Abstract:

Magnesium tetraphenylporphyrin (MgTPP) had been synthesized with tetraphenylporphyrin (TPP) and magnesium acetate according to reported paper. The photoanode of photoelectrochemical biofuel cell (PEBFC) was constructed including TiO₂ conductive film and photosensitizer Magnesium Tetraphenylporphyrin. The interaction between MgTPP sensitizer and TiO₂ was evaluated by X-ray photoelectron spectra, indicating that the MgTPP adsorbed on TiO₂ was easier to accept electrons compared with synthesized MgTPP itself. The spectroscopic properties of synthesized MgTPP and MgTPP-sensitization TiO₂ in dichloromethane solution were obtained by Uv-vis absorption spectra, demonstrating that the characteristic absorption peaks of MgTPP on TiO₂ displayed slight red shift compared with synthesized MgTPP. The photocurrent action spectrum evidenced that current of the PEBFC originated from MgTPP-sensitization TiO₂ photoanode.
