Abstract:
Herein, we designed selectively doped Co3O4 to explore the effect of coordination sites, in which the octahedral and tetrahedral sites were modulated by simple doping with ions of different radiuses (Al and In). Compared to octahedral regulation, the synergistic regulation of both tetrahedral sites and octahedral sites can induce a higher intrinsic activity, which is because they possess improved electrical conductivity and facilitate the formation of highly active Co3+/Co4+ species during the oxygen evolution reaction (OER).

In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

02:34Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can...

03:02Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...
