Under nitrogen atmosphere an unsaturated carbon-carbon double bond was hydrogenated to give a saturated one with nickel catalyst system(NiBr2/Zn/H2O/EtOH). It was found that hydrogen gas was generated from water and zinc powder by using metallic nickel catalyst, which was prepared from anhydrous nickel bromide and zinc powder. Metallic nickel was an active species for the reaction and zinc powder was a reagent to produce hydrogen. A probable pathway was presented.
