| 英文摘要 | Crystalline cu-based nanowire arrays (nwas) including cu(oh)(2), cuo, cu2o, and cuox are facilely grown on cu foil and are found to act as highly efficient, low-cost, and robust electrocatalysts for the oxygen evolution reaction (oer). impressively, this noble-metal-free 3d cu(oh)(2)-nwas/cu foil electrode shows the highest catalytic activity with a tafel slope of 86mvdec(-1), an overpotential () of about 530mv at approximate to 10macm(-2) (controlled-potential electrolysis method without ir correction) and almost 100% faradic efficiency, paralleling the performance of the state-of-the-art ruo2 oer catalyst in 0.1m naoh solution (ph12.8). to the best of our knowledge, this work represents one of the best results ever reported on cu-based oer systems. |
