Structure effects of self-assembled Prussian blue confined in highly organized mesoporous TiO2 on the electrocatalytic properties towards H2O2 detection

Here we report the derivatization of mesoporous TiO2 thin films for the preparation of H2O2 amperometric sensors. The coordination of the bifunctional ligand 1,10 phenantroline, 5,6 dione on the surface Ti(IV) ions provides open coordination sites for Fe(II) cations which are the starting point for...
