中文摘要	through layer-by-layer (lbl) assembly technique, iron oxide (fe3o4) nanoparticles coated by poly (diallyldimethylammonium chloride) (pdda) and preyssler-type polyoxometalates (nh4)(14)nap5w30o110.31h(2)o (p5w30) were alternately deposited on quartz and ito substrates, and 4-aminobenzoic acid modified glassy carbon electrodes. thus-prepared multilayer films were characterized by uv-visible spectroscopy, x-ray photoelectron spectroscopy, and cyclic voltammetry. it was proved that the multilayer films are uniform and stable. and the electrocatalytic activities of the multilayer films can be fine-tuned by adjusting the assembly conditions in the lbl assembly process, such as the ph of the assembly solution. the multilayer films fabricated from p5w30 solutions dissolved in 0.1 m h2so4 exhibit high electrocatalytic response and sensitivity toward the reduction of two substrates of important analytical interests, hno2 and io3- whereas the films assembled with p5w30 solutions dissolved in 1.0 m h2so4 show remarkable electrocatalytic activity for the hydrogen evolution reaction (her). furthermore, the electrocatalytic properties of the her of the latter film can be obtained from the former film upon exposure to 1.0 m h2so4 for several hours.
