The oxidation of 5-hydroxymethyl-2-furfural was studied under mild conditions using TiO2-supported Au and Au-Cu catalysts synthesized from preformed nanoparticles. Bimetallic gold-copper catalysts display a superior activity compared to monometallic gold supported catalysts. Moreover, after reaction, the bimetallic Au-Cu catalysts can be recovered by filtration and reused without any loss of activity and selectivity. In contrast, the monometallic gold catalysts are not stable under these reaction conditions. The effect of various reaction parameters was studied.

Abstract
The oxidation of 5-hydroxymethyl-2-furfural was studied under mild conditions using TiO2-supported Au and Au-Cu catalysts synthesized from preformed nanoparticles. Bimetallic gold-copper catalysts display a superior activity compared to monometallic gold supported catalysts. Moreover, after reaction, the bimetallic Au-Cu catalysts can be recovered by filtration and reused without any loss of activity and selectivity. In contrast, the monometallic gold catalysts are not stable under these reaction conditions. The effect of various reaction parameters was studied.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
