Hydrogen generation using PPy-FMS modified PVDF membrane and other substrates

Conducting polypyrrole (PPy) containing ferrocene monosulfonate (FMS) as counter-ion, was successfully electrodeposited onto Pt-coated PVDF membrane, Pt-coated PVDF hollow fiber, stainless steel mesh, and carbon fiber paper. Post-polymerisation cyclic voltammograms of these PPy-FMS-modified substrates showed that ferrocene had been incorporated into the polymer. Scanning electron microscopy (SEM) was employed to examine the morphology of PPy-FMS synthesized at different conditions. Hydrogen gas generation in 1.0 M H2SO4 using these different PPy-FMS-modified substrates demonstrated that the PPy-FMS-modified Pt/PVDF membrane exhibited the greatest catalytic effect.
