A Comparative Study of the Electrocatalytic Activities of Some Metal Hexacyanoferrates for the Oxidation of Hydrazine

The electrocatalytic properties of electrodes modified with metal [Cr(III), Mn(II), Fe(II), Co(II), Ni(II), Cu(II), Zn(II), Ag(I), Cd(II) and In(III)] hexacyanoferrates(II) were studied by cyclic voltammetry using hydrazine as substrate. The electrodes were prepared by mechanically transferring microparticles of the hexacyanoferrates onto the surface of a paraffin impregnated graphite electrode. The catalytic activities of these compounds were...
