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 (λ = 365 nm) of ZnO NWs under ethanol/water vapor flow at room temperature are related with the hydrogen production and carbon-containing products evolved.7 p.application/pdfengcc-by-nc-nd (c) Elsevier Ltd, 2023http://creativecommons.org/licenses/by-nc-nd/4.0/FotocatàlisiMetanolEspectroscòpia RamanPhotocatalysisMethanolRaman spectroscopyinfo:eu-repo/semantics/article7414462024-02-15info:eu-repo/semantics/openAccess
