Interferometric lithography is used to create 3D periodic photoresist structures that are then converted to carbon electrodes via pyrolysis (see image). The porous electrodes contain five patterned layers and engineered structures covering seven orders of magnitude in size scale. The electrochemical deposition of 1–3‐nm gold nanoparticles and catalytic activity towards methanol oxidation following electroless palladium deposition is demonstrated.
