AbstractKeggin Al-13[(Al4Al12(OH)(24)(H2O)(12)](7+) is a well-known efficient coagulant widely used in water purification and treatment. The production of high-content Al-13 is still costly, and it is therefore essential to develop new eco-efficient and low energy demand synthesis methods for practical application. Solid water interfaces play a dominant role in heterogeneous reactions, which can be utilized in various processes through rationally designed interfaces. Here, we designed an Al3+ and OH- interface by using NaOH-doped ice as a solid and AlCl3 solution as liquid for Al-13 production. This system provides a natural and renewable solid water interface through ice melting, while simultaneously minimizing external energy input and maintaining an effective heterogeneous interface reaction for production of high-quality Al-13 species. The dual-function of ice/water interface enables the formation of Al-13 with a high yield of up to 90% compared to initial total Al. Moreover, global areas with cold winter climate conditions may exploit this process reducing the need for external artificial method may have great potential for industrial mass production of Al-13. energy. As AlC3 can be obtained with low cost, this method may have great potential for industrial mass production of Al-13.
