Deep eutectic solvothermal NiS₂/CdS synthesis for the visible-light-driven valorization of the biomass intermediate 5-hydroxymethylfurfural (HMF) integrated with H₂ production

Abstract

Visible light driven transformation of biomass to high-valued chemicals is attractive for achieving a low-carbon society. The solar-catalyzed oxidation of 5-hydroxymethylfurfural (HMF) to 2,5-diformylfuran (DFF) has great industrial potential because...

Synergistically interactive MnFeM (M = Cu, Ti, and Co) sites doped porous g-C3N4 fiber-like nanostructures for an enhanced green hydrogen production

“…, CO 2 and CO), while green H 2 production through the HER occurs at room temperature and atmospheric pressure without environmental pollution. 9–11 However, with the aggravation of challenges in HER by using costly and rare-earth Pt-group catalysts, 14–18 it is necessary to exploit low-cost, green, and efficient catalysts to make the HER a competitive energy source on a commercial scale. Dedicated research efforts have come up with Pt-free catalysts, including metal nitrides, sulfides, phosphides, and oxides or their composites ( i.e.…”

“…[9][10][11] Hydrogen production methods like coal gasification and steam reforming 12,13 comprise excessive consumption of energy (i.e., 700-1100 °C and 3-25 bar) and fuels (i.e., natural gas), besides gas emissions (i.e., CO 2 and CO), while green H 2 production through the HER occurs at room temperature and atmospheric pressure without environmental pollution. [9][10][11] However, with the aggravation of challenges in HER by using costly and rareearth Pt-group catalysts, [14][15][16][17][18] it is necessary to exploit low-cost, green, and efficient catalysts to make the HER a competitive energy source on a commercial scale. Dedicated research efforts have come up with Pt-free catalysts, including metal nitrides, sulfides, phosphides, and oxides or their composites (i.e., Ni-Fe-P/NF 30 , NP-NiCo 2 O 4 , MoS 2 , and CoP 3 ).…”

Upgrading polyethylene terephthalate plastic into commodity chemicals paired with hydrogen evolution over a partially oxidized CuIn5S8 nanosheet photocatalyst

“…2d), where the S 2− characteristic peaks of O-CuIn 5 S 8 show a positive shift of 0.2 eV with respect to that of CuIn 5 S 8 . 44…”

“…2d), where the S 2− characteristic peaks of O-CuIn 5 S 8 show a positive shift of 0.2 eV with respect to that of CuIn 5 S 8 . 44 To investigate the light absorption capacity of the catalyst, UV-Vis diffuse reflectance spectra (UV-Vis-DRS) were recorded. As illustrated in Fig.…”

Deep eutectic solvents for catalytic biodiesel production from liquid biomass and upgrading of solid biomass into 5-hydroxymethylfurfural

“…4). Although some encouraging review works focusing on individual applications of DESs for biodie-sel preparation or solid biomass conversion have been reported, [54][55][56][57] to the best of our knowledge, there has been no joint review of specific applications of DESs for catalytic upgrading of liquid and solid biomass. Of great significance, it is anticipated that the eco-friendly application fields for DESs must be advanced to provide a more comprehensive perspective on the current development of DESs in biodiesel and HMF production.…”
