The effect of tellurium (Te) doping on the electrocatalytic activity of La1-xTe xMnO3 toward the oxygen reduction reaction is investigated for the first time. La1-xTe xMnO3 with x-values up 23% were synthesized from a single ionic liquid-based precursor, yielding nanoparticles with mean diameter in the range of 40-68 nm and rhombohedral unit cell. Electrochemical studies were performed on carbon-supported particles in alkaline environment. The composition dependence activity is discussed in terms of surface density of Mn sites and changes in the effective Mn oxidation state.
