Dianci bileiqi, 2021 研究了不同掺杂含量的Gd2O3对氧化锌（ZnO）压敏电阻片的电气性能、微观特性、物相特性和介电特性的影响。研究表明,掺杂Gd2O3对ZnO敏电阻片的电气性能具有重要影响,掺杂过量的Gd2O3对ZnO敏电阻片的晶粒生长具有抑制作用,锌填隙浓度提升,具体表现在电位梯度、泄漏电流提升而非线性系数大大减小。而掺杂少量的Gd2O3提升氧空位浓度,减小锌填隙浓度,进而抑制泄漏电流。此时掺杂量在0.5%（摩尔分数）Gd2O3电气参数分别为526 V/mm、15μA/cm2、非线性系数28 ...

Rare Metals, Volume 45, Issue 3, March 2026.ABSTRACT Platinum (Pt)‐based catalysts are crucial for the commercialization of hydrogen/metal air batteries, but they suffer from Pt scarcity, high cost, and nanoparticle dissolution/agglomeration, mainly leading to performance degradation. We address this by synthesizing a PtFe alloy catalyst (PtFe–PA–NC) via a phytic acid (PA) assisted pyrolysis ...
