One-dimensional (1D) ZnO nanostructures have been studied intensively and extensively over the last decade
not only for their remarkable chemical and physical properties, but also for their current and future diverse
technological applications. This article gives a comprehensive overview of the progress that has been made
within the context of 1D ZnO nanostructures synthesized via wet chemical methods. We will cover the synthetic
methodologies and corresponding growth mechanisms, different structures, doping and alloying, positioncontrolled
growth on substrates, and finally, their functional properties as catalysts, hydrophobic surfaces, sensors,
and in nanoelectronic, optical, optoelectronic, and energy harvesting devices.
