用浸碱热分解法制备了具有较高析氧活性和稳定性的复合氧化物ＮｉＣｏ＿２Ｏ＿４。考察了涂液成分、热分解温度和涂覆次数对ＮｉＣｏ＿２Ｏ＿４析氧活性的影响；测定了氧在ＮｉＣｏ＿２Ｏ＿４从电极上的稳态电化学行为。
The composite oxide NiCo_2O_4 with higher oxygen evolution activity and stability was prepared by the alkaline thermal decomposition method. The effects of coating composition, thermal decomposition temperature and coating times on the oxygen evolution activity of NiCo_2O_4 were investigated. The steady state electrochemical behavior of oxygen at NiCo_2O_4 electrode was measured.
