UiO-66-NH2/CeO2−x 异质界面添加剂使 PEMFC 单电池稳定运行超 500 h
Hetero‐Interface Maximized UiO‐66‐NH 2 /CeO 2−x Free Radical Scavenging Additives for Long‐Term Operation of Proton Exchange Membrane Fuel Cells
AI 导读
研究团队用种子介导生长在 UiO-66-NH2 表面制备缺陷氧化铈，构建 UiO-66-NH2/CeO2−x 异质结构以加速 Ce³⁺ 再生动力学。UiO-66-NH2 在 CeO2−x 生长过程中发生部分非晶化与溶解，形成紧密界面接触和增强的电子耦合，使该异质结构在氧化条件下的氧化还原循环与 Ce³⁺ 保持率优于商用氧化铈纳米颗粒。
