Rough it up: The efficiency of iron oxide electrodes for electrochemical water oxidation at neutral pH is optimized by macropore structuration, surface roughening, and phosphate incorporation. We use anodic alumina as a macroporous template, atomic layer deposition to coat the pore walls, and electrochemical treatments to increase the surface roughness and incorporate phosphate.

多孔氧化铁电极上析氧催化的设计规则：电流密度增加1000倍

粗略说明：通过大孔结构化，表面粗糙化和磷酸盐结合，可优化中性pH值下氧化铁电极用于电化学水氧化的效率。我们使用阳极氧化铝作为大孔模板，使用原子层沉积法覆盖孔壁，并使用电化学处理来增加表面粗糙度并掺入磷酸盐。
