The catalytic effect of monoclinic and tetragonal cerium-doped zirconias (m-CexZr1−xO2 and t-CexZr1−xO2, 0<x<0.10, respectively), prepared from gel precursors, on the oxidation of methylenedioxyamphetamine (MDA) and methylenedioxymetamphetamine (MDMA) at pH 7.0 has been studied. Upon attachment of synthetic specimens to polymer film electrodes, an oxidation peak near to +1.05 V vs AgCl/Ag appears that is unaffected by chloride ions and common interfering compounds, namely, dopamine, norepinephrine and ascorbic acid. The catalytic effect appears to be strongly influenced by crystallinity of specimens and coordination of cerium, increasing from the amorphous starting material to t-CexZr1−xO2 and m-CexZr1−xO2.
