| 英文摘要 | over the past several decades, tremendous effort has been put into developing cost-effective, highly active and durable electrocatalysts for oxygen evolution reaction (oer) in the proton exchange membrane water electrolyzer. this report explores an advanced and effective "soft" material-assistant method to fabricate ir0.6sn0.4o2 electrocatalysts with a 0.6/0.4 ratio of ir/sn in precursors. adopting a series of characterization methods, the collective results suggest that the surfactant-material f127 content, as an important factor, can efficiently control the formation of ir-sn oxides with varying surface properties and morphologies, such as the grainy and rod-shaped structures. associating with the half-cell and single electrolyzer, it is affirmed that the optimal ratio of (it + sn)/f127 is 100 for the preparation of s100-ir0.6sn0.4o2 with obviously enhanced activity and sufficient durability under the electrolysis circumstances. the lowest cell voltages obtained at 80 degrees c are 1.631 v at 1000 ma cm(-2), and 1.820 v at 2000 ma cm(-2), when applying s100-ir0.6sn0.4o2 oer catalyst and ti-material diffusion layer on the anode side and nafion (r) 115 membrane. furthermore, the noble-metal it loading in the same cell decreases to 0.77 mg cm(-2). these results highlight that ir-sn oxide synthesized by the soft-material method is a promising oer electrocatalyst.
