| 英文摘要 | pt-ceox/c electrocatalysts for the improvement of oxygen reduction reaction (orr) activity on cathode were prepared by a combined process of precipitation and co-impregnation methods. the pt-ceox/c electrocatalysts pretreated by the optimized electrochemical conditioning process showed high orr activity as compared with homemade pt/c electrocatalyst. also, it showed high stability in the cyclic voltammetry (cv) test up to 1000 cycles into 0.5 m h2so4 aqueous solution. on the basis of the data of cyclic voltammogram of 30 cyclic sweeps, x-ray photoelectron spectroscopy, electron energy loss spectroscopy, high resolution transmission electron microscope image, and selected area electron diffraction analysis, it is concluded that the pt-ceox heterointerface involving the defect cluster formed by using optimized electrochemical pretreatment conditions on pt in pt-ceox/c electro-catalyst contributes to the promotion of orr activity and retention of its stability in long cv tests up to 1000 cycles. |
