Ozone-Oxidation of Glucose to Formic Acid over Polyoxmetalates

The efficient oxidation of glucose to formic acid (FA) has emerged as a sustainable method for biomass utilization. Herein, we developed a new approach to fulfill oxidation of glucose to formic acid using a polyoxometalate (POM) K10SiW9Mn3IIO37/O3 system, and its high efficiency was presented with 79.3% yield of FA at 82.1% conversion at room temperature for 3 h. As evidenced by experiments, the components in Mn-POMs significantly influenced glucose conversion due to their effect on generating reactive oxygen species (ROSs) from O3, which was essential for FA production.
