摘要：

(Figure Presented) 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. © 2005 Wiley-VCH Verlag GmbH & Co. KGaA.
