, 2006 采用溶胶-凝胶法通过分步控制工艺制备了镍离子不同掺杂方式的TiO2薄膜.通过甲基橙的光催化降解动力学来表征其光催化活性.结果表明：镍离子非均匀掺杂在掺杂量0.5%时可以明显增强TiO2的光催化活性,而均匀掺杂提高TiO2的光催化活性较小.光电化学表征结果显示：镍离子非均匀掺杂TiO2薄膜的瞬时光电流信号较强,说明其光生载流子易于生成且分离效果较好;循环伏安曲线表明,光照时Ni非均匀掺杂的TiO2薄膜改变了体系的氧化还原电位,说明了薄膜内建电场的建立.基于半导体的P ...

Surface Reconstruction of Ce‐Ion‐Doped Fe‐MOF for Efficient Water Oxidation
Rare Metals, Volume 45, Issue 9, September 2026.ABSTRACT Surface reconstruction plays an important role in catalysts for the efficient oxygen evolution reaction (OER). In this work, we report the designed synthesis of the Ce‐ion‐doped Fe‐MOF (CFM) directly grown on nickel foam via a facile solvothermal route.
