Direct Oxidation of Glucose to Glucaric Acid Using Bimetallic AuPt/ZrO₂ Nanocatalysts.

ABSTRACT: Transforming biobased resources, such as glucose, into value-added chemicals is a crucial step in utilizing biomass. Herein, we report on the one-pot conversion of glucose to glucaric acid, by selectively steering the oxidation of glucose from the typical production of gluconic acid toward the production of glucaric acid, using monometallic Au and Pt and bimetallic AuPt nanocatalysts supported on zirconia. While the monometallic catalysts promote the production of gluconic acid, bimetallic catalysts favor the direct formation of glucaric acid from glucose, with efficacy depending on the Au/Pt ratio, reaching up to 44% selectivity with the Au_67%Pt_33%@ZrO₂ catalyst. Theoretical calculations confirm the formation of alloys, as experimentally evidenced by EDX-m
