Versatile Layered Hydroxide Precursors for Generic Synthesis of Cu‐Based Materials

The ability to mix multiple elements in a structure is crucial for obtaining Cu-based nanostructures and microstructures with desirable physicochemical properties. Precursors containing metal cations, such as layered double hydroxides, have been used the synthesis of multielement materials. However, these precursors experience difficulty large which limits functionalities derived Herein, development hydroxy salts (HDSs), versatile that accommodate broad range cations homogeneous distributions, reported. Up 25 different are mixed Cu an HDS single phase, individually simultaneously. HDSs further exhibit useful properties respect anion exchange, exfoliation, phase transformation oxides. During oxide process, formed crystal structures mainly dependent on ionic radius secondary cations. To prove their utility precursors, oxides from tested found they exhibited high catalytic activities CO oxidation. This study significantly expands compositional structural freedom multi-elemental
