This study addresses the selectivity issue in the conversion of biomass-derived furans to valuable chemicals by utilizing ZIF-8 nanoparticles, achieving high selectivity for the target compound. Computational studies based on chemisorption models of ZIF-8 provide a plausible explanation for the observed selectivity, paving the way for alternative and cost-effective strategies for green and sustainable developments in the chemical industry.
The conversion of biomass-derived furans to synthetically valuable chemicals is highly desirable but it remains a formidable challenge with regard to product selectivity, particularly in oxidative reactions. For example, the oxidative ring- opening of 2,5-dimethylfuran (DMF) using hydrogen peroxide as the oxidant proceeds in a nonselective manner, resulting in a multicomponent mixture along with the target compound (3-hexene-2,5-dione). In this work, we address the selectivity issue with a simple and efficient approach using zeolitic-imidazolate framework-8 nanoparticles (ZIF-8 NPs) as selectivity mediators on the base of their unique ordered structure. A quantitative conversion of DMF with 85% of selectivity to the target 3-hexene-2,5-dione (in comparison to 27% selectivity in the blank reaction) was achieved in the presence of ZIF-8 NPs, and importantly, under mild conditions (60 degrees C, and methanol as solvent). Furthermore, computational studies based on the chemisorption models of ZIF-8 demonstrated a plausible explanation of the observed selectivity. This work may pave the way toward the development of alternative and cost-effective strategies to improve product selectivity in biomass conversion with a view of green and sustainable developments in the chemical industry.
