Unconventional and Powerful Ion Sources for Solid-State Ion Exchange, Cu₂SO₄ and Cu₃PO₄: Exemplified by the Synthesis of Metastable β-CuGaO₂ from Stable β-LiGaO₂.

ABSTRACT: This study introduces a new method for synthesizing Cu⁺-containing metastable phases through ion exchange. Traditionally, CuCl has been used as a Cu⁺ ion source for solid-state ion exchanges; however, its thermodynamic driving force is often insufficient for complete ion exchange with Li⁺-containing precursors. First-principles calculations have identified Cu₂SO₄ and Cu₃PO₄ as more powerful alternatives, providing a higher driving force than CuCl. It has been experimentally demonstrated that these ion sources can open up new reaction pathways through experimental ion exchanges, such as from β-LiGaO₂ to β-CuGaO₂, which were previously unattainable. An important perspective provided by this stu
