Abstract

A high-entropy layered hydroxide (HELH), in which Mg²⁺, Al³⁺, Co²⁺, Ni²⁺, Zn²⁺ were homogeneously distributed on two dimensions sheets, was synthesized for the first time. The HELH shows moderate thermal stability and hydroxide ion conductivity up to 10⁻³ S cm⁻¹. This finding presents tremendous opportunities for emerging new two-dimensional high-entropy materials.
