摘要

超薄氧化膜超薄（2.5 - 10nm）无定形Al2O3电极涂层抑制电化学O2还原，同时允许缓慢的质子传输。在文章2400846中，Georgios Katsoukis及其同事通过红外反射吸收和电化学阻抗谱测定了质子扩散系数，并揭示了产生新的质子传输途径的阴极重构。对硅酸铝的基准测试强调了在选择性、渗透性和涂层厚度方面的基本权衡。

Mechanistic Insights Into Proton and Oxygen Transport Through Ultrathin Amorphous Al2O3 and Al2O3-SiO2 Electrocatalyst Overlayers (Adv. Mater. Interfaces 13/2025)

Ultrathin Oxide Membrane

Ultrathin (2.5 – 10 nm) amorphous Al₂O₃ electrode coatings suppress electrochemical O₂ reduction while allowing slow proton transport. Through IR reflection-absorption and electrochemical impedance spectroscopy, in article 2400846, Georgios Katsoukis and co-workers determine proton diffusion coefficients and reveal cathodic restructuring that generates new proton transport pathways. Benchmarking against aluminosilicate highlights essential trade-offs in selectivity, permeability, and coating thickness.
