Renewable, clean and portable energy source through waste retrieval is the necessity of the world. The current work demonstrates the recycling and activation of waste Al cans through the active support of numerous metals and an in-depth probe of their co-catalytic impact on H₂ generation. The results showed that hollow Al microspheres with several defects, grain boundaries offered micro galvanic cells through inner-outer surface embedded Cr particles. The rapid corrosion of the entire Al microsphere elevated hydrogen production via the aid of magnetic transition and ionization of Cr at varied temperatures and the continuous elimination of the oxide layer. The reaction kinetics revealed a kinetically monitored hydrolysis reaction of Al-97.5/Cr-2.5 in 1 M NaOH solution with the H₂ production of 673.12 mL and activation energy Ea = 17.92 kJ mol⁻¹. The predicted mechanism defines the synergism and corrosion/anti-corrosion roles of Al and Cr throughout the hydrolysis. Through these structurally-mechanically-chemically engineered routes, the waste management perspective claims the potential candidature to clean energy pathways.

通过废物回收获得可再生、清洁和便携的能源是世界的必需品。目前的工作证明了废铝罐的回收和活化通过多种金属的活性支持以及它们对 H ₂生成的共催化影响的深入探讨。结果表明，具有多种缺陷、晶界的空心铝微球通过内外表面嵌入的 Cr 颗粒提供微原电池。整个 Al 微球的快速腐蚀通过 Cr 在不同温度下的磁转变和电离以及氧化层的连续消除来提高氢气的产生。反应动力学揭示了 Al-97.5/Cr-2.5 在 1 M NaOH 溶液中与 H ₂673.12 mL 的产量和活化能 Ea = 17.92 kJ mol ^-1。预测的机制定义了铝和铬在整个水解过程中的协同作用和腐蚀/防腐作用。通过这些结构-机械-化学工程路线，废物管理的观点声称具有清洁能源途径的潜在候选资格。
