Abstract
The metal-organic framework MIL-101(Cr) is known as a solid-acid catalyst for the solution conversion of biomass-derived glucose to 5-hydroxymethyl furfural (5-HMF). We study the substitution of Cr3+ by Fe3+ and Sc3+ in the MIL-101 structure in order to prepare more environmentally benign catalysts. MIL-101(Fe) can be prepared and inclusion of Sc is possible at low levels (10 % of Fe replaced). On extended synthesis times the polymorphic MIL-88B structure instead forms. Increasing the amount of Sc also yields only MIL-88B even at short crystallisation times. The MIL-88B structure is unstable under hydrothermal conditions, but in dimethylsulfoxide solvent it provides 5-HMF from glucose as the major product. The optimum material is a bimetallic Fe,Sc form of MIL-88B, which provides ~70 % conversion of glucose with 35 % selectivity towards 5-HMF after 3 hours at 140 oC: this offers high conversion compared to other heterogeneous catalysts reported in the same solvent.
