Free-Standing Porous Cu-Based Nanowires as Robust Electrocatalyst for Alkaline Oxygen Evolution Reaction
Abstract Cu-based catalysts have emerged as important candidates for oxygen evolution reaction (OER) electrocatalysts. Based on $ Mg_{72} $$ Cu_{28} $ alloy ribbon, a free-standing porous Cu hydroxide/oxide nanowires (p-CuNWs) was fabricated by a combined method of chemical dealloying and electroche...

| 520 | |a Abstract Cu-based catalysts have emerged as important candidates for oxygen evolution reaction (OER) electrocatalysts. Based on $ Mg_{72} $$ Cu_{28} $ alloy ribbon, a free-standing porous Cu hydroxide/oxide nanowires (p-CuNWs) was fabricated by a combined method of chemical dealloying and electrochemical treatment. The structure and chemical state of p-CuNWs were characterized by X-ray diffraction pattern analysis, scanning electron microscopy, and X-ray photoelectron spectroscopy. The p-CuNWs were identified as mixed Cu(OH)2 and CuO with a high active surface area, which exhibit robust activity for OER in alkaline solution with an overpotential of only 377 mV to offer current density of 50 mA $ cm^{−2} $, small Tafel slope of 85 mV $ dec^{−1} $. The catalytic durability of p-CuNWs was also evaluated by cyclic voltammetry cycles and a small decay of activity was observed. Graphical Abstract | ||

Free-Standing Porous Cu-Based Nanowires as Robust Electrocatalyst for Alkaline Oxygen Evolution Reaction |
| abstract |
Abstract Cu-based catalysts have emerged as important candidates for oxygen evolution reaction (OER) electrocatalysts. Based on $ Mg_{72} $$ Cu_{28} $ alloy ribbon, a free-standing porous Cu hydroxide/oxide nanowires (p-CuNWs) was fabricated by a combined method of chemical dealloying and electrochemical treatment. The structure and chemical state of p-CuNWs were characterized by X-ray diffraction pattern analysis, scanning electron microscopy, and X-ray photoelectron spectroscopy. The p-CuNWs were identified as mixed Cu(OH)2 and CuO with a high active surface area, which exhibit robust activity for OER in alkaline solution with an overpotential of only 377 mV to offer current density of 50 mA $ cm^{−2} $, small Tafel slope of 85 mV $ dec^{−1} $. The catalytic durability of p-CuNWs was also evaluated by cyclic voltammetry cycles and a small decay of activity was observed.
