Hydrogen spillover assisted by oxygenate molecules over nonreducible oxides

open access: yesNature Communications, 2022
Spontaneous migration of H-atoms from metal particles to a nonreducible oxide support is generally limited by thermodynamics. Here, small oxygenate molecules are found to act as effective H-carriers to promote this process and lead to much improved ...

Identification of Key Aroma Compounds Responsible for the Floral Ascents of Green and Black Teas from Different Tea Cultivars

open access: yesMolecules, 2022
Chemicals underlying the floral aroma of dry teas needs multi-dimensional investigations. Green, black, and freeze-dried tea samples were produced from five tea cultivars, and only ‘Chunyu2’ and ‘Jinguanyin’ dry teas had floral scents.

Single-pass transformation of syngas into ethanol with high selectivity by triple tandem catalysis

open access: yesNature Communications, 2020
Direct synthesis of ethanol from non-petroleum carbon resources via syngas (CO/H2) is a highly attractive but challenging target. Here, the authors report a triple tandem catalytic system for single-pass conversion of syngas into ethanol with selectivity

Direct conversion of methane to formaldehyde and CO on B2O3 catalysts

open access: yesNature Communications, 2020
Partial oxidation of methane to value-added C1 products remains challenging due to the favorable formation of fully-oxidized CO2. Here, the authors show supported B2O3 catalysts with tri-coordinated BO3 units as the active site are highly selective in ...

Synthesis of α-hydroxy-β,β-difluoro-γ-ketoesters via [3,3]sigmatropic rearrangements [PDF]

open access: yes, 2000
Readily available γ,γ-difluorinated allylic alcohols obtained from trifluoroethanol were esterified efficiently. Exposure to strong base (LDA) afforded the ester enolates, in which chelation both controlled configuration and stabilised against ...
