Abstract: Based on the coupling of molecular imprinting, chitosan biosorption, and nano TiO2 photocatalysis technologies, a novel core-shell organic-inorganic hybrid material of surface imprinted chitosan-TiO2 composite (SICT) was prepared with methyl orange as the template. SEM, EDS, AFM, pore size analysis, and FTIR characterization results illustrated that TiO2 nano powder was successfully coated on the surface of chitosan microparticles via intermolecular hydrogen bonds to form the core-shell organic-inorganic composites with rough and porous surface morphology. SICT showed enhanced photocatalytic selectivity for methyl orange (M.O.) compared with the non-imprinted chitosan-TiO2 composites because of the existing of more suitable sites generated by surface molecular imprinting. The removal of M.O. by SICT was mainly from the photocatalytic degradation rather than simple adsorption. SICT could be reused directly without further desorption and regeneration for 10 cycles with preserving 60% of its photocatalytic efficiency. The reusability of SICT would be beneficial for the simplification of the operating steps and the cost reduction which facilitated its practical applications in wastewater treatment concerning environmental organic pollutants
