Ultrasonication-assisted synthesis of ternary-component Ni 3 Al x Fe 1−x -layered double hydroxide nanoparticles for the oxygen evolution reaction in a neutral solution

In this study, ultrasonication, a facile and rapid process, was utilized for the preparation of ternary-component layered double hydroxides (LDHs), Ni 3 Al x Fe 1−x -LDHs, as the electrocatalyst material for the oxygen evolution reaction (OER) in a neutral solution.
