摘要：The selective oxidation of glycerol to valuable lactic acid (LA) is a typical cascade catalytic process in biomass conversion. The present study demonstrates that K addition into Pt/Sn-MFI can promote the selectivity in the selective oxidation of glycerol to LA, with glycerol conversion of 92.8% and LA selectivity of 86.2% in a base-free solution. Comprehensive experimental and characterization studies reveal that K+, not only acts as the electron donor for Pt nanoparticles, promoting the oxidation of secondary hydroxyl groups of glycerol to dihydroxyacetone (DHA), but also mediates the acid/base properties for Pt/Sn-MFI, facilitating the dehydration, 1,2-hydride shift and hydration of DHA to LA. This work not only presents an elegant showcase of achieving a synergistic effect by modulating the microenvironment but also provides a rational approach to enhance the catalytic performance in the selective oxidation of glycerol. ? 2025 Elsevier B.V.
