Abstract
The effect of the platinum particle size was investigated for the cata lytic oxidative dehydrogenation of aqueous ethanol to ethanal at a tem perature of 303 K, an ethanol concentration of 260 mol m(-3), a partia l oxygen pressure 60 kPa, a pH of 9, and an ethanal and ethanoate conc entration of 20 mol m(-3). A particle size effect on the turnover freq uency was observed but only for particle sizes smaller than 2 nn. Henc e, the reaction shows a limited structure sensitivity.
