首次研究了碲（Te）掺杂对La_（1-x）TexMnO_3对氧还原反应的电催化活性的影响。由单一离子液体为基础的前体合成了x值高达23%的La 1-xTexMnO 3，得到平均直径在40-68 nm范围内的纳米颗粒和菱形晶胞。在碱性环境中对碳载粒子进行了电化学研究。的组成依赖性的活动进行了讨论，在Mn网站的表面密度和有效锰氧化态的变化。
The effect of tellurium (Te) doping on the electrocatalytic activity of La1-xTexMnO3 toward the oxygen reduction reaction is investigated for the first time. La1-xTexMnO3 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.
