The oxalic acid-assisted fast pyrolysis of biomass for the sustainable production of furfural

Coproduction of 1,4:3,6-Dianhydro-α-d-glucopyranose, Furfural, and Formic Acid through Oxalic Acid-Assisted Staged Fast Pyrolysis of Cellulose

“…Theoretically, the decomposition of OA has two ways, one producing FA and CO 2 , and the other producing CO 2 , CO, and H 2 O. According to the abundant FA and CO 2 obtained in primary pyrolysis (Figures and S4), it is deduced that the former way was the main decomposition channel of OA, consistent with the lower energy barrier of the former way in our previous DFT calculations . As for the esterification reactions, OA can esterify with the hydroxyl groups located at C2, C3, and C6 positions of the cellulose backbone unit .…”

Cross-polymerization between bio-oil and polyaniline: synergistic effects on pore development in subsequent activation and adsorption of phenol

“…14 To tackle this issue, Hu et al proposed crosspolymerization of bio-oil with furfural, which remarkably enhanced the yield of carbonaceous material. 15 Furfural can be produced from biomass via hydrolysis or pyrolysis, [16][17][18] and opening of its furan ring during hydrolysis generates reactive intermediates, [19][20][21] facilitating polymerization of the organics in bio-oil. Nonetheless, furfural will not work in the preparation of heteroatoms such as N-doped carbon material from bio-oil.…”

Ni(OH)2 surface-modified hierarchical ZnIn2S4 nanosheets: dual photocatalytic application and mechanistic insights

“…[7][8][9] In particular, furfural (FF) derived from furfuryl alcohol (FA) is an important chemical raw material, which has been widely used in synthetic rubber, medicines, pesticides, and other fields. [10][11][12][13][14] For example, FF can be converted to levulinic acid to bridge the gap between the biomass feedstock, and the hydrogenation products of FF have been recognized as versatile multifunctional platform molecules. [15][16][17] Therefore, coupling photocatalytic FA oxidation to produce FF with H 2 evolution under anaerobic conditions is a promising scheme to make the full use of the photogenerated electrons and holes simultaneously and thus meet the economic and social sustainability goals.…”
