Abstract: A TiO2/carbonized resin (B) complex nanocatalyst has been synthesized by using a simple method by molecule design and characterized with regard to their components, structure, size, and photo-catalytic properties. The results show that the average size of TiO2/Bcomplex nanoparticles composed of C, H, Oand Ti elements is about 30 nm, The stacking structure of Ti and Oin the complex belongs to TiO2anatase. Bwith different lengths of conjugated chains, and TiO2are chemically bound and their absorption is in an whole UV-Vis region. The TiO2/B complex nanomaterial is strong polar, resulting in efficient separation of photogenerated charges related to efficiency of light conversion and photocatalytic activities closely. The material is ideal and promising for photoelectric conversion and photocatalysis.

Key words: TiO2/carbonized resin, Nanophotocatalyst, Photocatalytic decolorization, Acridine orange
