| 英文摘要 | we developed an advanced surfactant-assistant method for the irxsn1-xo2 (0 < x <= 1) nanoparticle (np) preparation, and examined the oer performances by a series of half-cell and full-cell tests. in contrast to the commercial ir black, the collective data confirmed the outstanding activity and stability of the fabricated irxsn1-xo2 (x = 1, 0.67 and 0.52) nps, which could be ascribed to the amorphous structure, good dispersion, high pore volume, solid-solution state and ir-rich surface for bi-metal oxides, and relatively large size (10-11 nm), while ir0.31sn0.69 exhibited poor electro-catalytic activity because of the separated two phases, a sno2-rich phase and an iro2-rich phase. furthermore, compared with highly active iro2, the improved durability, precious-metal ir utilization efficiency and correspondingly reduced ir loading were realized by the addition of sn component. when the ir0.52sn0.48o2 cell operated at 80 degrees c using nafions (r) 115 membrane and less than 0.8 mg cm(-2) of the noble-metal ir loading, the cell voltages we achieved were 1.631 v at 1000 ma cm(-2), and 1.821 v at 2000 ma cm(-2). the ir-free voltage at the studied current density was very close to the onset voltage of oxygen evolution. the only 50 mu v h(-1) of voltage increased for the 500 h durability test at 500 ma cm(-2). in fact, these results are exceptional compared to the performances for oer in spewe cells known so far. this work highlights the potential of using highly active and stable iro2-sno2 amorphous nps to enhance the electrolysis efficiency, reduce the noble-metal ir loading and thus the cost of hydrogen production from the solid polymer electrolyte water electrolysis. |
