The Confinement of Hydrogen in LaNi5 Hydride Using Surface Poisoning

Abstract It has been found that an LaNi5 hydride treated with a CO gas is stable in air at room temperature. The hydrogenation of acetophenone or 1-octene was performed using the CO-treated hydride. The reaction well proceeded and it was confirmed that hydrogen confined in the hydride can be available for reactions. The use of the CO-treated LaNi5 hydride, therefore, can simplify the operation for hydrogenation.
