Claims36
A composition, comprising:
- an aluminum alloy comprising less than or equal to 50 weight percent (wt. %) silicon (Si) and/or less than or equal to 50 wt. % magnesium (Mg) based on a total weight of the aluminum alloy, and wherein the aluminum alloy comprises an activating composition comprising gallium (Ga), and wherein the Ga is concentrated proximate to grain boundaries of the aluminum alloy.
A method, comprising:
- exposing a surface of an aluminum alloy to an activating composition comprising gallium, wherein the aluminum alloy comprises less than or equal to 50 weight percent (wt. %) silicon (Si) and/or less than or equal to 50 wt. % magnesium (Mg) based on a total weight of the aluminum alloy;
- and
- permeating the activating composition through one or more grain boundaries and/or subgrain boundaries of the aluminum alloy for an amount of time.
A method of producing hydrogen gas, comprising:
- exposing an activated aluminum alloy to water, wherein the activated aluminum alloy comprises less than or equal to 50 weight percent (wt. %) silicon (Si) and/or less than or equal to 50 wt. % magnesium (Mg) based on a total weight of the activated aluminum alloy, and wherein the activated aluminum alloy comprises an activating composition comprising gallium (Ga), and wherein the Ga is concentrated proximate to grain boundaries of the activated aluminum alloy;
- and
- producing hydrogen gas.
