A patterned ZnO nanorod array/gas sensor fabricated by mechanoelectrospinning-assisted selective growth†
Abstract
Micropatterned ZnO nanorod arrays were fabricated by the mechanoelectrospinning-assisted direct-writing process and the hydrothermal growth process, and utilized as gas sensors that exhibited excellent Ohmic behavior and sensitivity response to oxidizing gas NO2 at low concentrations (1–100 ppm).
