Polypyrol film was deposited on SS304by employing CPCvoltametery method, then coated with nano TiO2 (PPy/TiO2)and used as a photocatalysis for degradation of somedyesacid fushin, methylenblue, methyl orange and methyl red. The SEM and XRD analysis indicated nano size of TiO2 deposits as 20nm on the polypyrol film. The UV result of absorption revealed that this film increased the rate of degradation of dyes comparing with TiO2 powder
