What is it about?

Iron oxides are widely studied, while the iron oxide dimer and its carbonyl complexes lacked to gain enough research interest. The present study explores the dimers in various configurations - peroxides and dioxides with varying magnetic interactions, their relative stability, and the ability of the dimers and their carbonyl complexes to split water.

Why is it important?

It is important to know how can iron oxides split water, and what energy is required, compared to the iron sulfides, for which experimental evidence is available.

Perspectives

Our study proves that fine tuning of the catalyst for water splitting is possible by varying the type of compound - oxide or sulfude, and the type of ligand. the methods used in the present stydy allow us to evaluate a large number of clusters and molecular complexes as catalysts and photocatalysts for this reaction.
