Abstract：

In this work, porous CNTs/Fe-Ni/TiO2 photo-catalyst composite film was assembled on FTO conducting glass substrate. Firstly, nickel and iron doped titanium dioxide sol precursor containing block polymer P123 was prepared by sol-gel method. Then, Fe-Ni/TiO2 porous film on FTO conductive glass substrate was prepared using the spray pyrolysis deposition technique. Finally, CNTs were in situ grown on Fe-Ni/TiO2 porous film by chemical vapor deposition (CVD) method, to prepare a nickel and iron doped CNTs/TiO2 porous composite film. The CNTs/Fe-Ni/TiO2 porous composite film photocatalyst was characterized by X-ray diffraction, field emission scanning electron microscopy, transmission electron microscopy), Raman spectra and photo-current responses. The photocatalytic activity and stability were investigated by photodegradation of methyl orange. The results show that the optimized photocatalytic performance activity was achieved when the time of CVD was 20 min and the temperature is 550-600 ℃.
