NOVELTY - A hydrogen generating material comprises 0-10 wt.% molybdenum sulfide-epitaxial graphene and balance magnesium-nickel alloy. The ratio of molybdenum sulfide to epitaxial graphene is 1-2:1. USE - Hydrogen generating material. ADVANTAGE - The hydrogen generating material increases the activity of the surface of the magnesium-rich alloy particles due to the addition of surface active layered nano material, inhibits the formation of surface magnesium oxide and effectively destroys the integrity of the magnesium hydroxide colloidal product film by layered structure during hydrogen production. The hydrogen generating material provides convenient channel for medium diffusion and transmission, improves the initial hydrogen production kinetics of magnesium-rich alloys and increases the hydrogen production yield of magnesium-rich alloys. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of hydrogen generating material which involves compounding metal magnesium block having purity of greater than or equal to 99.8 wt.% and magnesium-nickel intermediate alloy with magnesium loss of 5-8 wt.%, placing in pre-baked high-purity graphite crucible, heating, stirring to obtain uniform magnesium-rich alloy melt, further heating, stirring, casting into a preheated steel mold, air cooling to room temperature to obtain magnesium rich-nickel alloy ingot, placing the magnesium rich-nickel alloy ingot in an argon-protected closed ball mill tank in a ratio of 15-30:1, refining the particles by high-energy vibrating ball milling process to obtain alloy powder and adding the alloy powder and molybdenum sulfide-epitaxial graphene to the ball mill tank for high-energy ball milling to achieve surface composite nano-modification.
