Abstract
Modification of carbon electrodes with first row transition metal phth alocyanines results in the lowering of the potentials needed for water electrolysis in basic media, by 600 to 700 mV when compared to unmodi fied carbon electrodes. Nickel(II), cobalt(II) and iron(II) phthalocya nines show higher catalytic activity than zinc(II), manganese(II), cop per(II) and metal free phthalocyanines.
