| Outline of Research at the Start |
Conventional pathway to access 5-hydroxymethylfurfural (HMF) derivatives relies on using unstable and expensive HMF as starting feedstock. This research aims to achieve one-pot direct synthesis of HMF derivatives from cheap and abundant fructose without energy-intensive isolation of HMF by designing tandem catalysts containing both acids and hydrogenation active sites. The strength of acids and metal active sites will be adjusted based on the demand of HMF hydrogenation or hydrogenolysis products. This study contributes to the scope of sustainable utilization of biomass.

| Outline of Annual Research Achievements |
The direct conversion of cellulose-derived fructose to 5-hydroxymethylfurfural (HMF) hydrogenated derivatives is of importance considering the sustainable utilization of biomass. As we have previously found that FeOx modified Cu/SiO2 catalyst presented high selectivity towards the hydrogenation of C=O bonds while leaving C-OH unchanged, producing 2,5-bis(hydroxymethyl)furan (BHMF) as the main products. The Cu-FeOx/SiO2 catalyst was then further modified via various methods in order to introduce Bronsted acid on the catalyst to access the dehydration of fructose to HMF. We found that by the modification by using Na2HPO4, desired acid sites were loaded on the catalyst and showed the activity for the formation of BHMF form fructose, although the yield was slightly lower compared to that in the literatures.

Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
The effort has been made for the acid modification of the Cu-FeOx/SiO2 catalyst to achieve the direct formation of 2,5-bis(hydroxymethyl)furan (BHMF) from fructose. Modification by using Na2HPO4 gave desired the performance however, the acidity was slightly moderate and further improvement the acidity is necessary to achieve high activity.
|
| Strategy for Future Research Activity |
The next strategy to achieve the goal of this study is to further improve the acidity of the Cu-FeOx/SiO2 catalyst to enhance the activity of fructose dehydration to HMF. Furthermore, the production of 2,5-dimethylfuran (DMF) from fructose will also be investigated. We have found that FeOx modified Ru/SiO2 catalysts were confirmed to be effective for the C-O bond cleavage, which was good for the hydrogenolysis of HMF to 2,5-dimethylfuran (DMF). Therefore, acid modification will also be conducted to Ru-FeOx/SiO2 catalyst to achieve fructose dehydration to DMF. The results will be prepared and submitted to the international journal.
