Bringing the promises of microreactors and gold catalysis to lignocellulosic biomass valorization: A study on oxidative transformation of furfural

Influence of Oxide Coating Layers on the Stability of Gold Catalysts for Furfural Oxidative Esterification to Methyl Furoate

“…In Figure 6a, it can be observed that both catalysts still exhibit a major phase of Zn 6 Al 2 O 9 , similar to the fresh catalysts, indicating the phase structure of catalysts will not be changed over the reaction process. Nevertheless, the UV-vis spectra in Figure 6b reveal a significant wavenumber redshift in the plasmon resonance of gold over the Au/ZA catalyst, suggesting the probable agglomeration of gold nanoparticles over the Au/ZA catalyst [18]. To further confirm this, TEM characterization was also conducted on the spent Au/ZA and Au@SiO 2 /ZA-1 catalysts.…”

“…One notable downstream product derived from FF is methyl 2-furoate (MF), which finds extensive applications in the fine chemical industry, including flavors, fragrances, extracting agents, and chemical intermediates [16][17][18][19][20]. The conventional approach for the industrial synthesis of MF involves esterification of 2-furoic acid (FA) with alcohols, where FF is initially oxidized to FA using potent stoichiometric oxidants like KMnO 4 [19,20].…”

Highly efficient electrocatalytic oxidation of furfural to maleic acid over MOF-derived MnCeOx

“…[1][2][3][4][5] Furfural, a promising biomass-derived C5 compound, has long been considered a versatile precursor to synthesize numerous value-added chemicals. [6][7][8][9] In this regard, partial oxidation of furfural to produce maleic acid (MA) has attracted much attention for a long time [10][11][12][13][14] because MA is a critical chemical intermediate having extensive applications in surface coating, 15 polyester resins, 16 agriculture chemicals and lithium ion batteries. 17,18 Currently, oxidation of furfural to synthesize MA is mainly conducted in vapor-phase and liquid-phase systems.…”
