It is of great importance to understand the origin of high oxygen-evolving activity of state-of-the-art multimetal oxides/(oxy)hydroxides at atomic level. Herein we report an evident improvement of oxygen evolution reaction activity via incorporating iron and vanadium into nickel hydroxide lattices....
On the other hand, the Y-Al distance as well as the number of Al atoms coordinating Y is close to the values predicted by the DRP model. These anomalous changes around the Fe atoms indicate a strong interaction between Fe and Al, which corroborate a covalent bonding. In connection with ...
The additions of a number of heteroatomic nucleophiles, including methanol, amines, phosphines, phosphites and thiols to dicarbonyl-η 5-cyclopentadienyl(olefin)iron cations are reported. These reactions generally occur with high regio-specificity to monosubstituted olefin complexes, affording a single ad...

The eigenfunction expansions for the target ions include 13 levels up to the for Fe XXV, and 16 levels up to the for Fe XXVI, respectively. The calculated number of bound levels, 83 for Fe XXIV and 138 for Fe XXV, is much larger than experimentally observed. The level energies are in ...
