X Ray Absorption Spectroscopy Structural studies of metal hexacyanoferrates-based mediators for H2O2 detection

X-ray absorption spectroscopy (XAS) is applied for the study of the local geometry of Fe, Ni, and Pd sites hexacyanoferrates modified electrodes used for the electrochemical detection of hydrogen peroxide in real matrices. The XAS technique permits to check the local charge associated to the metals, and to investigate their local structure, of the electrodes prior and after the addition of H2O2
