Summary: In this research, the effect of temperature on the hydrolysis reaction of recycled aluminum for hydrogen production was evaluated. The study found that the highest production of H-2 occurred at 50 degrees C, with a purity of 93.33%. However, at room temperature, the reaction efficiency was still high, with a production of 660 mL of H-2 in 268 s. The physicochemical characterization of the solid residues showed that they contained aluminum, sodium, and oxygen, with the main crystalline phases being aluminum hydroxide and sodium aluminum oxide hydrate. Overall, the production of H-2 from recycled aluminum at room temperature was found to be a viable option for clean power generation with lower energy consumption and financial costs compared to traditional technologies.
