文摘
Several hetero-junction nanocomposites consisting of N- and P-type semiconductors and conductor (γ-Fe2O3, polypyrrole and silver) were prepared here by radical polymerization and redox method for adsorptive and photocatalytic applications. The obtained materials were characterized by means of X-ray diffraction, scanning electron microscopy, energy-dispersive X-ray spectroscopy, Infrared spectroscopy, and ultraviolet–visible absorption measurement. The results indicated that the average size of γ-Fe2O3 nanoparticles from all the samples is approximately 26.5?nm, the Ag nano-crystal with a average size of 19.2?nm attached on the interface of γ-Fe2O3 and the polypyrrole or polypyrrole surface and has good dispersivity. The adsorptive and photocatalytic activities of the above composites were studied before and after 2?h photodegradation of Methyl Orange and Orange II. Considering the adsorptive and photocatalytic performances as a whole, Fe2O3/polypyrrole composites based on the P–N-type hetero-junction exhibited the highest removal ability towards azo dyes compared with all the other as-prepared samples, and the total removal ratios towards Methyl Orange and Orange II were 84.3 and 92.6?%, respectively.
