钙钛矿型氧化物因其具有相对较高的OER催化活性,成为了电解水阳极催化剂的热门材料之一.采用溶胶—凝胶法合成LaCuO_(3)钙钛矿型氧化物,通过Co,Ni元素掺杂提高电催化剂的催化活性.通过X射线衍射(XRD),扫描电子显微镜(SEM)和能量色散谱(EDS)表征以及稳态极化(LSV),循环伏安(CV),电化学阻抗谱(EIS)等电化学测试分析,...
The anomaly of the g factors and local structure for LaCuO are theoretically investigated from the perturbation formulas of the g factors for a 3 d ion in tetragonally distorted tetrahedra based on the cluster approach including the ligand contributions. The anomaly ( g...
