Recent advances in the molecular-level understanding of catalytic hydrogenation and oxidation reactions at metal-aqueous interfaces

Solvent-Modulated Multiple Active Hydrogen Species in Furfural Hydrogenation

“…Although the correlation between active hydrogen species transfer and the characteristics of metal oxide supports has been extensively studied, 9−11 the catalyst-dependent solvent effects have not received sufficient attention. 12 Specifically, a different selectivity in furfural hydrogenation reactions has been found in water over reducible and nonreducible oxide supported metal nanoparticle catalysts. 13 The Grotthuss-like mechanism in aqueous hydrogenation has demonstrated that water directly takes part in hydrogenation by picking up a metal-adsorbed H* and the formed H 3 O + transfers the proton to substrates or active sites by H-bond networks.…”
