摘要/Abstract

摘要： 用热分解法制得不同混合比例的二元金属氧化物催化剂Co_xCr_1-xO_3/2（x = 0，0.2，0.4，0.6，0.8，1），使用SEM、XRD和XPS观察表征催化剂形貌、晶型和价态，使用线性扫描伏安、阶梯波伏安和恒电位测试电极活性、过电位和稳定性. 结果表明，该Co₃O₄和绿铬矿型Cr₂O₃混合物形成固溶体Co_xCr_1-xO_3/2. x = 0.2时，Co_0.2Cr_0.8O_3/2电极性能较单一Co₃O₄和Cr₂O₃电极好，在高电位（1.0 V vs. Ag/AgCl），其电流强度是Co₃O₄的3.75倍，Cr₂O₃的15.2倍，其过电位（η = 0.0703 V）也较Co₃O₄（η = 0.6109 V）和Cr₂O₃（η = 0.435 V）小，催化性能最好，在强碱性溶液（pH=13）中有良好的稳定性.

Abstract: Binary metal mixed oxides of Co and Cr with nominal compositional formulas, Co_xCr_1-xO_3/2 (x=0, 0.2, 0.4, 0.6, 0.8 and 1.0), were obtained by thermal decomposition method. The morphologies, crystal forms and valence states of the catalyst powders were analyzed by SEM, XRD and XPS, respectively. And the electrochemical properties, overpotentials and stabilities of Co_xCr_1-xO_3/2 electrodes for oxygen evolution reaction (OER) in an alkaline solution were evaluated by linear sweep voltammetry (LSV), staircase voltammetry and chronoamperometry, respectively. The results indicated that the mixtures of Co₃O₄ and eskolaite-Cr₂O₃ formed solid solutions of Co_xCr_1-xO_3/2. When x=0.2, the electrocatalytic performance of Co_0.2Cr_0.8O_3/2 catalyst was better than those of Co₃O₄ and Cr₂O₃. At high potential region (1.0 V vs. Ag/AgCl), the current density of Co_0.2Cr_0.8O_3/2 catalyst was 3.75 times higher than that of Co₃O₄ and 15.2 times higher than that of Cr₂O₃. Furthermore, the overpotential of Co_0.2Cr_0.8O_3/2 catalyst (η = 0.0703 V at a current density of 1×10^-3 A·cm^-2) was much lower than those of Co₃O₄ (η = 0.6109 V) and Cr₂O₃(η = 0.4350 V), showing the best electrocatalytic property. In addition, the Co_0.2Cr_0.8O_3/2 catalyst had good stability in strong alkaline solution (pH = 13) during OER process.
