Nanoporous materials with a uniform pore morphology and exquisite pore accessibility are functional materials of enormous importance in various application areas. These include primarily catalytic and sensory applications, energy storage, but also wastewater treatment. Spinodal demixing is a phase separation mechanism that provides direct access to these desired nanoscale morphologies if arrested in its early stages. However, only melts, alloys, and polymeric systems have been nanostructured via this pathway up to this day; it is a widely accepted tenet that aqueous solutions of inorganic compounds cannot be phase-separated via these pathways. This project aims to demonstrate that, under readily achievable chemical conditions—namely, in systems that spontaneously form coordination clusters—spinodal demixing of aqueous solutions is readily feasible, contrary to expectation. This project will develop this phase-separation route, long deemed inaccessible, into a synthesis methodology based on fast-flow-chemistry that is exploitable for the scalable synthesis of nanoporous inorganic solids.

具有均匀孔形态和独家孔隙可及性的纳米多孔材料是各种应用领域中重要性增强的功能材料。这些包括主要的催化和感觉应用，储能，还包括废水处理。 Spinodal解散是一种相分离机制，如果在早期阶段被捕，可以直接访问这些所需的纳米级形态。但是，迄今为止，只有融化，合金和聚合系统才通过该途径进行纳米结构。无机化合物的水溶液不能通过这些途径分离。该项目的目的是证明，在易于实现的化学条件下（即，在赞助商形成协调簇的系统中）水溶液的质合解散是可行的，与期望形成鲜明对比。该项目将发展为基于快速化学化学的合成方法，发展为长期以来无法访问的相位分离途径，该方法可利用纳米型无机固体的可扩展合成。
