| Abstract Scope |
Presented is an investigation of the use of scrap aluminum reacted with seawater to produce hydrogen and heat. Seawater is used to promote the agglomeration of a gallium-indium eutectic (eGaIn) that disrupts the aluminum passivation layer, allowing nearly full recovery and reuse of the eGaIn. Results show that the inclusion of 0.02M imidazole in seawater increases the reaction rate by a factor of sixty while enabling 92% eGaIn recovery and yielding 99% of the theoretical hydrogen output from the aluminum-water reaction. A pre-processing method is introduced to activate scrap aluminum, enhancing the material's reactivity for hydrogen generation. |
