“…The hydrolysis of saccharides requires sufficient acid strength, and is an important class of reaction, used to convert biomass into bioethanol and other useful chemicals with minimal environmental impact. [17,18] Ionexchange resins, such as [18e] have strong sulfonic acid sites and as a result are powerful catalysts for the hydrolysis of saccharides. Niobic acid (Nb 2 O 5 ·n H 2 O) is a unique solid acid resistant in water solution.…”

“…[5] Moreover, due to its similar structure to terephthalic acid (PTA)-a monomer for the production of polyethyleneterephthalate (PET plastic)-renewable FDCA obtained from biomass has a great potential to replace PTA. [6][7][8][9][10] Therefore, the exploration of the efficient oxidation of HMF and production of FDCA is a significant and commercially viable alternative process to the petroleum approach.…”

Au nanoclusters with an average size of approximately 1 nm size supported on HY zeolite exhibit a superior catalytic performance for the selective oxidation of 5‐hydroxymethyl‐2‐furfural (HMF) into 2,5‐furandicarboxylic acid (FDCA). It achieved >99 % yield of 2,5‐furandicarboxylic acid in water under mild conditions (60 °C, 0.3 MPa oxygen), which is much higher than that of Au supported on metal oxides/hydroxide (TiO2, CeO2, and Mg(OH)2) and channel‐type zeolites (ZSM‐5 and H‐MOR). Detailed characterizations, such as X‐ray diffraction, transmission electron microscopy, N2‐physisorption, and H2‐temperature‐programmed reduction (TPR), revealed that the Au nanoclusters are well encapsulated in the HY zeolite supercage, which is considered to restrict and avoid further growing of the Au nanoclusters into large particles. The acidic hydroxyl groups of the supercage were proven to be responsible for the formation and stabilization of the gold nanoclusters. Moreover, the interaction between the hydroxyl groups in the supercage and the Au nanoclusters leads to electronic modification of the Au nanoparticles, which is supposed to contribute to the high efficiency in the catalytic oxidation of HMF to FDCA.

“…[1] To avoid conflicts with food production, as seen in the last few years, nonfood biomass should be used as a resource for the production of chemicals. Cellulose is the most abundant nonfood biomass resource produced via photosynthesis, [2] and therefore the conversion of cellulose has attracted significant attention as a key issue in the utilization of biomass.…”
