Topological anionic confinement enables synthesis of 2D high-entropy molybdates under mild conditions (opens in new tab)

Two-dimensional high-entropy materials offer vast opportunities, yet their low-temperature synthesis with compositional homogeneity and anisotropic morphology remains challenging, due to thermodynamic competition between entropy-driven mixing and strain-induced phase segregation. Here we report a topological anionic confinement strategy that uses MoO42− tetrahedra as spatially defined scaffolds to suppress cation segregation. This strategy enables the single-step, template-free synthesis of a...
