electronic configurationlayeredspin configurationsCo 3+Ni 3+oxidesIn La 4LiCoO 8, Li + and Co 3+ ions are ordered in two dimensions and Co 3+ ions undergo transitions from the low-spin to the intermediate as well as the high-spin states. Both Sr 4TaCoO 8 and Sr 4NbCoO 8 exhibit ...
Each octahedrally coordinated cobalt ion is forced into a low-spin electron configuration by the anionic oxo and carboxylato ligands, and a fractional electron hole is localized on each metal center in a Co 3dxz,yz-based molecular orbital for this essentially [Co+3.1254O4] system. Comparing ...
Electronic configuration is crucial for enhancing the catalytic activities of spinels for the oxygen evolution reaction (OER). However, controlling the electronic spin state of materials is still a challenge. In this work, we synthesized Fe-doped meso-Co3O4via a nanocasting method. The merit of ...
