摘要：

A series of porous Co1-xFexOy (0 <= x <= 1) nanorods were fabricated by a simple thermal decomposed of CoFe-NTA precursors and were served as oxygen evolving catalysts for water electrolysis in 1 mol KOH solution. It was found that different Fe doping amounts have dramatically effects on the structure and electrocatalytic water oxidation activities and the 16% (n/n) Fe-doping sample exhibited the most excellent oxygen evolving activity. A lowered overpotential of 345 mV was achieved at a current density of 10 mA .cm(-2) with a Tafel slope of 54 mV.dee(-1) for the 16% Fe-doping sample, which suggest that it can he applied as low cost and efficient oxygen catalyst for water splitting.
