Abstract
Gold based catalysts over different supports were investigated in the oxidative esterification of furfural by employing an efficient and sustainable process. The catalytic performances follow the trend: Zirconia-Au > Ceria-Au > > Titania-Au. Zirconia came out to be the best support option to promote activity, selectivity and also stability. The chemical and morphological properties observed for zirconia supported sample seem to fulfil a good compromise between high gold dispersion and the presence of suitable acid-base properties, for good selectivity. Moreover, stability and recycling of the catalysts were also investigatedFile | Dimensione | Formato | |
