High‐porosity, single‐crystal ZnO nanowires have been synthesized for the first time using a solid–vapor process on a Si substrate. The thermal decomposition of ZnO and the formation of a Zn 2 SiO 4 network on the nanowire surface are the keys for forming the high‐porosity interior. The structures exhibit a very high surface‐to‐volume ratio and are expected to have high absorptive capacity and chemical selectivity that could be used for filter and sensor systems.
