ZnO NWs were characterized by FESEM, XRD, HRTEM, XPS, PL and Raman spectroscopy and used as photocatalysts for the photo-transformation of ethanol(aq) in the gas phase. The existence of different defects such as oxygen vacancies was evidenced. The photocatalytic process was followed by in-situ diffuse reflectance infrared spectroscopy (DRIFTS) coupled to on-line mass spectrometry (MS) analysis. The surface species determined during the irradiation (\u03bb = 365 nm) of ZnO NWs under ethanol\/water vapor flow at room temperature are related with the hydrogen production and carbon containing products evolved.<\/p>\n<p>NanoEnergy (<a href=\"https:\/\/www.ub.edu\/in2ub\/grup-de-recerca\/catalysis-and-advanced-inorganic-materials\/\" target=\"_blank\" rel=\"noopener\">Catalysis and Advanced Inorganic Materials<\/a>) &amp; NanosMat (<a href=\"https:\/\/www.ub.edu\/in2ub\/grup-de-recerca\/materials-for-energy-photonics-and-catalysis\/\" target=\"_blank\" rel=\"noopener\">Materials for Energy, Photonics and Catalysis (ENPHOCAMAT)<\/a>) Research Areas collaboration<\/p>\n<p><a href=\"https:\/\/doi.org\/10.1016\/j.ijhydene.2023.11.360\" target=\"_blank\" rel=\"noopener\">H2\u00a0generation from aqueous ethanol over ZnO nanowires, the photo-transformation of surface species<\/a>.\u00a0<em>N.\u00a0Homs,\u00a0A.
