A new TiO₂/polyfurfurylamine(CPFA) nanocomposite was successfully prepared via a process,known as in-situ two-step method(in-situ TSM),from monomer furfurylamine(FA) and TiO₂ and used as catalyst to degrade dye MB molecules.The effects of the factors,such as the heat treatment and TiO₂ content,on the catalytic property were investigated.Catalytic experiments indicated that under natural light and room temperature conditions,the MB solution was fully decolorized on TiO₂/CPFA nanocomposite particles within 2 min.And TiO₂/CPFA nanocomposite particles with 42.48% of TiO₂,treated at 460℃,exhibited much higher catalytic activity and could keep very high activity on MB decolorization reaction when it was repeatedly used 3 times.TEM results show that in-situ TSM was successful for preparing TiO₂-conjugated polymer nanomaterial and the size of TiO₂/CPFA particles was about 26 nm and the size distribution was very narrow.XRD results show that TiO₂ of the composite material was a mixture of rutile and the content of rutile was about 79%.
