Reaction kinetics investigation of the selective oxidation of aqueous ethanol solutions with air over a Au/TiO2 catalyst

► Kinetics of selective oxidation of aqueous ethanol with air over Au/TiO2 catalyst. ► The gold catalyst was characterized by N2 physisorption, XRD, ICP-OES, and TEM. ► The experimental data were adequately fitted into a LHHW kinetic model. ► H abstraction by a surface hydroxyl species is assumed to be the RDS.
