【 摘 要 】

In order to decrease the decomposition voltage of hydrogen evolution in ordinary alkaline or acidic water and simultaneously degrade the Ethanolamine (MEA) sewage, the efficient hydrogen evolution assisted by MEA electro-oxidation over nickel nanowire arrays anode is investigated in this work. The nickel nanowire arrays anode is successfully fabricated with the aid of the polycarbonate template and the low-melting point alloy. The electrochemical results show the driving voltage to deliver the same current density of 20 mA cm-2 in the 1.0 mol L-1 KOH/0.05 mol L-1 MEA solution is lowered by 12.2% than that in 1.0 mol L-1 KOH solution. The present study proves the viability to produce hydrogen efficiently by electrolyzing the MEA-containg water.
