During CO2/HCO3– reduction with renewable biomass, achieving high-efficiency production of the target products is vital but challenging. In this study, an NH2– functional-group-modified MIL-53(Fe) catalyst was synthesized using a facile and efficient method. Under action NH2-MIL-53(Fe) catalyst, clear synergistic effect exhibited on transformation glucose NaHCO3 into formic acid high yield 50% at low reaction temperature (190 °C) via three-pronged route, which mainly involved decomposition intermediates to gradually reduce under hydrothermal conditions. An in-depth analysis catalytic mechanism density functional theory calculations demonstrated that increased alkalinity active sites by group incorporation system enhanced crucial steps reduced activation energy reactions, including isomerization, aldehyde intermediate retro-aldol condensation, redox compounds acid, thereby promoting generation suppressing side products. This study addresses challenge reducing from biomass commercial constructing multifunctional sites, thus providing new strategy for carbon cycling.
