Leaky layers: Several 10 μm‐thick, highly aligned, porous structures of titanium dioxide, niobium pentoxide and mixed oxides can be grown anodically in nitrate‐containing electrolytes with channel diameters in the range of 10–20 nm. Depending on the substrate, the electrochemical growth parameters need to be optimized to achieve a high degree of long‐range order.
