Visible-light-driven anaerobic oxidative upgrading of biomass-derived HMF for co-production of DFF and H₂ over a 1D Cd_0.7Zn_0.3S/NiSe₂ Schottky junction

Abstract

Visible-light-driven photocatalytic oxidation of renewable biomass into value-added chemicals is a prospective solar energy utilization strategy. However, the aerobic oxidation reactions commonly generate uncontrolled reactive oxygen species, which leads to...

Efficient NADH Regeneration without Electron Mediator toward Enzymatic CO2 Reduction Enabled by a Lawn-like TP-COFs/Ti3C2Tx (MXene) Photocatalyst

“…Converted by eq S4, the E CB (vs. the RHE) = E (Ag/AgCl) + 0.197 + 0.059 × pH (pH = 7.0). Namely, the E CB potentials of TC and TCM-15% were estimated to be −0.67 and −0.70 V (vs. NHE, pH = 0, eq S5), respectively. ,,,, Integrated with their bandgaps, the valence band ( E VB ) potentials of TC and TCM-15% were calculated to be 1.27 and 1.13 V (vs. NHE), respectively.…”

“…The bandgap ( E g ) of TC and TCM-15%, estimated using the Kubelka–Munk function, are 1.94 and 1.83 eV, respectively (Figure b). , Mott–Schottky (M-S) plots were carried out to determine the band structures of the samples. In Figure c and Figure d, both the as-synthesized TC and TCM-15% show a positive slope in their M-S plots, which is a characteristic feature of n -type semiconductor. − Therefore, the detected flat band potentials can be roughly identified as the E CB potentials. − The E CB of TC and TCM-15% were determined to be −1.28 and −1.31 V, respectively, through the tangent of the curve (vs. Ag/AgCl, pH = 7.0). Converted by eq S4, the E CB (vs. the RHE) = E (Ag/AgCl) + 0.197 + 0.059 × pH (pH = 7.0).…”

High-efficiency visible-light-driven oxidation of primary C–H bonds in toluene over a CsPbBr3 perovskite supported by hierarchical TiO2 nanoflakes

“…It can be found that the 20%CPB/TiO 2 sample has the minimum arc radius, which means the best electronic conductivity and charge separation ability. 56,57 Furthermore, the steady-state photoluminescence (PL) spectra are also used to examine the charge separation efficiency. As shown in Fig.…”

Photocatalytic upgrading of 5-hydroxymethylfurfural – aerobic or anaerobic?

“…Yang et al developed a one-dimensional Schottky junction Cd 0.7 Zn 0.3 S/NiSe 2 by in situ growth of NiSe 2 sheets on Cd 0.7 Zn 0.3 S nanorods through chemical vapor deposition. 90 Cd 0.7 Zn 0.3 S nanorods can effectively transfer electrons over long distances to cocatalyst NiSe 2 for HER while inhibiting back flow and prolonging the lifetime of charge carriers. In contrast to one-step hole-driven ODH, HMF is first deprotonated by strong polar solvent ( e.g.…”
