Hierarchical micro‐/nano‐structures made easy . By using extremely rough, chemically etched microstructured aluminium foils, anodization in phosphoric acid under very harsh conditions, e.g., 10 wt% phosphoric acid and room temperature, can be repeatedly accomplished without suffering from breakdown. As a result, an alumina membrane with a three‐dimensionally distributed nanopore structure is formed, which can be used as a general template to fabricate hierarchical micro‐/nano‐structures.
