Abstract
The larger surface area and increased point contacts of hierarchically arranged ZnO nanowires (upper panel) offered more potential barriers for the gas molecule exhibiting binding strength CO < C<sub>2</sub>H<sub>5</sub>OH < NH<sub>3</sub> (lower panel) and provided excellent gas-sensing performance at 100 °C for NH<sub>3</sub> gas.
