Abstract EN
Ce doped RGO-TiO2 composite films on ITO substrates were prepared by sol-gel process using tetrabutyl titanate and reduced graphene oxide (RGO) as the starting materials.
The sample was designed for the photoelectrocatalytic applications.
The obtained samples were characterized by X-ray diffraction, UV-vis absorption spectroscopy, scanning electron microscopy, and Fourier transformed infrared spectroscopy.
The results showed that doping of Ce on RGO-TiO2 composite film inhibited the TiO2 anatase-rutile phase transformation.
In this case, Ce atoms could serve as dispersion oxide and suppress the recombination of photoinduced electron-hole pairs.
Besides, the change in absorbance from UV to visible region was observed in Ce doped RGO-TiO2 nanocomposite films.
The Ce doped RGO-TiO2 composite film showed higher photoelectrochemical performance than that of RGO-TiO2 composite and pure TiO2 under solar simulator irradiation.
The main reason might be attributed to the optimum content of Ce that could act as electrons acceptor to hinder the recombination loss and facilitate the better transportation for photoinduced charge carriers.
