Abstract	Ultraviolet (UV) irradiation is a promising approach for enhancing a sensing response in metal oxide-based molecular sensor, however, its substantial impact on the molecular-to-surface interaction at ...sensor surface is poorly understood. In this study, we investigated the UV irradiation effect on adsorption state of volatile aldehyde at single crystalline zinc oxide (ZnO) nanowire surface by Fourier transform-infrared spectroscopy (FT-IR). A C9 aliphatic aldehyde, nonanal, was employed as an analyte. We found that oxidation of adsorbed nonanal was significantly promoted by the UV irradiation. A wavelength dependence implied that the photogenerated carriers play a crucial role in the enhanced oxidation. Our finding would be beneficial for designing the performances of metal oxide nanowire-based molecular sensing devices.show more
