Photocatalysis Property of Titania-based Thin Films with Covalent Grafting PANi as Sensitizer
Polyaniline sensitized titania thin film were fabricated by spin-coating from Ti-precursor containing PEG as surfactant via a sol-gel technique,in which titania-sol was synthesized by hydrolysis of tetrabutyl titanate in water-alcohol solution.The films were characterized by X-ray diffraction,high resolution transmission electron microscopy,field-emission scanning electron microscopy,thermal gravity-differential scanning calorimetry,and tested under self-made photocatalysis instrument.The results showed the synthesized porous films provided the active surfaces for self-polymerization of aniline.Compared with bare TiO2 thin films,the composite films displayed a enhanced photocatalytic activity and could be the potential photocatalyst for indoor air decontamination or self-cleaning films.
