kinetic measurements of reacting species
Catalysts are complex systems of carrier materials doped with transition metal compounds that accelerate chemical reactions. Analysing them specifically proves difficult for most analytical methods which rely on X-rays or light the infrared, visible or ultraviolet spectrum. In contrast to that ESR sees only the paramagnetic centers through the ESR-silent surrounding.
Kitae et al. (2015) observed the spontenous formation of oxygen in a solution of Mn5O8 nanoparticles at neutral pH. This oxygen evolution reaction (OER) was investigated by means of ESR. The ESR spectra indicated that Mn3+ is the active center, which catalyzes the OER.
