| Outline of Annual Research Achievements |
The formation of 5-hydroxymethylfurfural (HMF) hydrogenated derivatives through direct transformation of fructose is essential for green and sustainable utilization of biomass. Last year, various metal-supported catalysts were synthesized and evaluated for the activities to hydrogenation of HMF. Cu/SiO2 catalyst, compared to other noble metals, showed high selectivity towards the hydrogenation of C=O bonds but leaving C-OH unchanged, producing 2,5-bis(hydroxymethyl)furan (BHMF) as the main products. Furthermore, the modification of Cu/SiO2 by FeOx, which promoted the dispersion of Cu active sites on the catalyst surface, greatly improved the hydrogenation activity with 99% BHMF formation at 99% HMF conversion under mild conditions.

Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
In the past year, effective FeOx modified Cu/SiO2 catalysts were successfully synthesized which showed high selectivity for the formation of BHMF from HMF. By using this catalyst combined with further modification by acid, the formation of BHMF via firstly dehydration of fructose to HMF and subsequent hydrogenation of HMF could be achieved.
|
| Strategy for Future Research Activity |
In the next step, the acid modification of the synthesized Cu-FeOx/SiO2 catalyst will be performed to introduce Bronsted acid on the catalyst to access the production of BHMF from fructose. Moreover, FeOx modified Ru/SiO2 catalysts were confirmed to be effective for the C-O bond cleavage, which will be further investigated for the hydrogenolysis of HMF to 2,5-dimethylfuran (DMF). And the acid modification will also be conducted to achieve the transformation of fructose to DMF.
The results on the hydrogenation of HMF to BHMF will be prepared and submitted to the international journal.

| Causes of Carryover |
Because of the change of affiliation, the plan for using the budget has been slightly reconsidered. And most of the conferences were held online last year, leading to some unused amount from travel expenses.
The remaining amount will be used to buy necessary equipment and chemicals in this fiscal year.
