The influence of calcination temperature on the electrocatalytic properties of thermally-prepared (Ni_0.4Co_0.6)_0.90Ir_0.10-oxide and (Ni_0.4Co_0.6)_0.90Ru_0.10-oxide in the oxygen evolution reaction (OER) was investigated in an alkaline medium. It was shown that by lowering the calcination temperature, the OER activity of the two materials increased significantly, yielding a maximum at 300 °C. The increase in electrocatalytic activity of the oxides was related to the change in intrinsic properties of the anodes, predominantly to the modification of the electronic structure and to the increase in hydroxide content. The (Ni_0.4Co_0.6)_0.90Ir_0.10-oxide was found to significantly outperform the current state-of-the-art OER electrocatalyst, pure Ir-oxide, while the electrocatalytic activity of (Ni_0.4Co_0.6)_0.90Ru_0.10-oxide was measured to be much higher than that of the Ni_0.4Co_0.6-oxide base, thus demonstrating the synergistic action of Ni/Co/Ir and Ni/Co/Ru in their oxides.

煅烧温度对热制备(Ni _{0 . 4} Co _0.6 ) _0.90 Ir _{0.10 -}氧化物和(Ni _{0 . 4} Co _0.6 ) _0.90 Ru _{0.10电催化性能的影响}在碱性介质中研究了析氧反应 (OER) 中的 -氧化物。结果表明，通过降低煅烧温度，两种材料的 OER 活性显着增加，在 300 °C 时达到最大值。氧化物电催化活性的增加与阳极本征性质的变化有关，主要与电子结构的改变和氢氧化物含量的增加有关。发现 (Ni _{0 . 4} Co _0.6 ) _0.90 Ir _{0.10 -}氧化物显着优于当前最先进的 OER 电催化剂，纯 Ir-氧化物，而 (Ni _{0 . 4} Co _0.6) _0.90 Ru _{0.10 -}氧化物被测量为远高于Ni _{0 。4} Co _{0.6 -}氧化物碱，因此证明了Ni/Co/Ir和Ni/Co/Ru在它们的氧化物中的协同作用。
