A network of platinum nanotubes with diameters of about 15 nm and walls 1 nm thick that interconnect to form an open, doubly bicontinuous structure (see high‐resolution electron micrograph) is formed by coating platinum on a nanoporous gold template then dissolving away the mold. The structure is stable at 125 °C for at least 24 hours, but starts to deform at 150 °C and eventually forms nanoparticles.
