中文摘要 | tetrakis (n-methylpyridyl) porphyrinato] cobalt (cotmpyp) and 1:12 silicotungstic acid (siw12) were alternately deposited on a 4-aminobenzoic acid (4-aba)-modified glassy carbon electrode through a layer-by-layer method. the resulting organic-inorganic hybrid films were characterized by cyclic voltammetry (cv) and uv/vis absorption spectroscopy. we proved that the prepared multilayer films are uniform and stable. siw12-containing multilayer films (siw12 as the outermost layer) exhibit remarkable electrocatalytic activity for the hydrogen evolution reaction (her). the kinetic constants for her were comparatively investigated at different layers of siw12/cotmpyp multilayer film-modified electrodes by hydrogen evolution voltammetry. in addition, rotating disk electrode (rde) and rotating ring-disk electrode (rrde) voltammetric methods confirm that siw12/cotmpyp (cotmpyp as the outermost layer) multilayer films catalyze almost a two-electron reduction of o-2 to h2o2 in ph 1-6 buffer solutions. furthermore, p2w18/cotmpyp films were also assembled, and their catalytic activity for her is very different from that of siw12/cotmpyp multilayer films. |
