| 中文摘要 | the multi-walled carbon nanotubes (mwnts) modified glassy carbon electrode exhibited electrocatalytic activity to the reduction of oxygen in 0.1 m hac-naac (ph 3.8) buffer solution. further modification with cobalt porphyrin film on the mwnts by adsorption, the resulted modified electrode showed more efficient catalytic activity to o-2 reduction. the reduction peak potential of o-2 is shifted much more positively to 0.12 v (vs. ag/agcl), and the peak current is increased greatly. cyclic voltammetry (cv), transmission electron microscopy (tem), x-ray photoelectron spectroscopy (xps) and atomic force microscopy (afm), were used to characterize the material and the modified film on electrode surface. electrochemical experiments gave the total number of electron transfer for oxygen reduction as about 3, which indicated a co-exist process of 2 electrons and 4 electrons for reduction of oxygen at this modified electrode. meanwhile, the catalytic activities of the multilayer film (mvvnts/cotmpyp)(n) prepared by layer-by-layer method were investigated, and the results showed that the peak current of o-2 reduction increased and the peak potential shifted to a positive direction with the increase of layer numbers. |
