Solid state catalytic hydrogen exchange for deuterium in cycloprolylglycine

The reaction of spillover hydrogen (SH) with cyclopropylglycine (cPG) in high-temperature solid-state catalytic hydrogen isotope exchange (HTCIE) has been studied experimentally and using density functional theory (DFT). NMR spectroscopy and mass spectrometry have shown a high regioselectivity and stereoselectivity for the reaction of spillover hydrogen with cPG fragments. The Gly fragment has been shown to be the most reactive in HTCIE, for which high stereoselectivity of substitution of hydrogen by deuterium has been demonstrated.

Enhanced hydrogen spillover to fullerene at ambient temperature

Enhanced hydrogen spillover on molecular fullerene C60, which represents extremely curved graphene sheets, is experimentally demonstrated around ambient temperature. Since the spillover hydrogen is strongly attracted by C60, the increase of C60mass can be directly confirmed by mass spectroscopy.

Mild-temperature hydrodeoxygenation of vanillin over porous nitrogen-doped carbon black supported nickel nanoparticles

N-doped carbon black (NCB) supported Ni NPs exhibited higher activity than most Ni-based catalysts for selective HDO of vanillin at mild conditions, ascribing to higher reducibility, lower oxidation state of Ni NPs and enhanced spillover hydrogen of Ni to NCB.

Effect of the components' interface on the synthesis of methanol over Cu/ZnO from CO2/H2: a microkinetic analysis based on DFT + U calculations

During the methanol synthesis over Cu/ZnO catalysts, the phase interface was observed to supply spillover hydrogen to active copper sites.
