Photoassisted hydrogen generation by integrated electroactive SPE membranesystem

Incorporation of TiO2 into perfluoroionomer membrane by treatment with TiCl 4-methanol has been described. Platinum was used as an electrocatalyst. In order to make the system electronically as well as ionically conducting, th e electrode was modified with polypyrrole (PPy). Photopolymerisation of pyr role was accomplished by immersing TiO2-Pt-NaF in pyrrole solution. UV-visi ble and FT-IR Spectroscopic studies were preformed with regards to the form ation of the TiO2. Pt and PPy within Nafion matrix. We report the construct ion and evaluation of this integrated system and establish the feasibility of hydrogen generation thereof.
