Abstract
Described herein are aluminum-based alloy compositions useful for generating hydrogen gas upon contact with water or water containing liquids. The aluminum-based alloys generate hydrogen quickly by reacting with water at room temperature through the formation of galvanic cells. The alloys are mainly composed of aluminum and other metals selected from the group containing chromium (Cr), copper (Cu), iron (Fe), magnesium (Mg), manganese (Mn), silicon (Si), titanium (Ti), zinc (Zn), and/or zirconium (Zr).
Claims14
A method of generating hydrogen gas, the method comprising:
- contacting in an aqueous solution an aluminum-based alloy comprising aluminum, chromium, copper, iron, magnesium, manganese, silicon, titanium, and zinc,
- optionally further comprising zirconium,
- wherein the aluminum is present between 90% to 99%, 85% to 99%, 80% to 99%, 70% to 99%, 60% to 99%, 50% to 99%, or 40% to 99%, and
- wherein chromium is present between 0.01% to 0.5%, 0.01% to 0.45%, 0.01% to 0.4%, 0.01% to 0.35%, 0.02% to 0.35%, 0.03% to 0.35%, or 0.04% to 0.35%, to produce the hydrogen gas.
