TiO₂ paper (TP) photocatalysts were prepared using filter paper template. Then PPy/TP composites were synthesized via unstirred in-situ polymerization on TiO₂ paper. The characterizations of the samples obtained under different conditions were characterized by FTIR, SEM, X-ray diffractometry, and UV-vis spectroscopy. By the methyl orange degradation, the effect of the polymerization time and PPy modification on the photocatalytic property of PPy/TP was investigated. The results indicated that PPy/TP was paper-like and composed of interwoven modified TiO₂ microbelts|the shift of the absorption edge into the visible-light range with the narrowing of the band gap and the photocatalytic efficiency of PPy/TP was higher than that of TP|and PPy/TP-40 had the highest efficiency for the polymerization time of 40 min.

Key words: PPy, filter paper, titanium dioxide, methyl orange, sunlight
