摘要	In this work, doped and substituted polyaniline (PANI)-coated Fe3O4 nanoparticles were synthesized. The diameter of Fe3O4 core was similar to 430 nm, and the thickness of PANI shell was similar to 20 nm. Their photo-catalytic properties for methyl orange were investigated under natural light illumination. The photo-catalytic activity sequence of three doped PANI/Fe3O4 nanoparticles is as follows: iodine doping > without doping > graphite powder doping This should be due to the difference of structure, conductivity, and band gap resulting from the dopants. The photo-catalytic activity of five substituted PANI/Fe3O4 nanoparticles followed the order of poly(1,2-diaminobenzene) > poly(o-toluidine) > poly(1,3-diaminobenzene) > PANI > polydiphenylamine. The effects of steric hindrance, activated ability, and conjugation of the substituents on the photo-catalytic properties were discussed. The ESR results suggested that O-2 and H2O2 dissolved in the solutions were important factors on the photo-degradation, and the center dot OH generated via h(+)-mediated pathwaywas the key oxidizing substance.
