In situ X-ray absorbance spectroscopy measurements show that encapsulating cobalt phthalocyanine within coordinating polymers leads to axial ligation of Co and results in enhanced rates for electrocatalytic CO 2 reduction.
A Cr K-edge XAS study of paradigmatic chromium porphyrin and corrole derivatives has been carried out, providing key data for the Cr( iv ) and Cr( v ) oxidation states.
Platinum L 3 -edge XAS and DFT calculations on three well-characterized Pt porphyrinoid complexes have provided detailed insights into metal- versus ligand-centered oxidation and ligand field effects.
In photosynthetic systems employing multiple transition metal centers, the properties of charge-transfer states are tuned by the coupling between metal centers.
Novel σ– α method, applied under non-steady state conditions, enables an accelerated and detailed study of oxygen vacancy and small polaron transport in praseodymium doped ceria as functions of oxygen non-stoichiometry and temperature.
