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 ...

Biosynthesized Ag/α-Al2O3 catalyst for ethylene epoxidation: the influence of silver precursors [PDF]

open access: yesRSC Advances, 2014
Biosynthesized Ag/α-Al2O3 catalysts toward ethylene epoxidation were prepared with Cinnamomum camphoratrees (CC) extract using AgNO3, silver–ammonia complex ([Ag (NH3)2]+) and silver–ethylenediamine complex ([Ag(en)2]+) as the silver precursors.

Efficient Ru–Fe catalyzed selective hydrogenolysis of carboxylic acids to alcoholic chemicals† [PDF]

open access: yesRSC Advances, 2014
Supported bimetallic Ru–Fe catalysts were prepared using a step-deposition–reduction method. The selective hydrogenolysis of acetic acid to ethanol was investigated as a reaction, which is considered to be related to the transformation of biomass-derived

Effects of Organic Acids on the Release of Fruity Esters in Water: An Insight at the Molecular Level

open access: yesMolecules, 2022
It is well known that organic acids (OAs) could affect the flavour of fruit juices and beverages. However, the molecular mechanism of aroma release is still unclear. In this study, the effects of citric acid (CA), L-(-)-malic acid (MA) and L-lactic acid (
