Kinetics of L-arabinose oxidation over supported gold catalysts with in situ catalyst electrical potential measurements

Abstract

The kinetics of L-arabinose selective oxidation over Au/Al 2O 3 catalysts was studied with simultaneous in situ catalyst electrical potential measurements. An oxidative dehydrogenation mechanism was proposed and a kinetic model taking into account the catalyst potential changes was developed. The kinetic model was implemented into the three-phase system and validated with the experimental observations. The agreement of the kinetic model to the experimental data, in line with the suggested reaction mechanism, was satisfactory. © 2012 The Royal Society of Chemistry.
