Pulsed‐Laser Ablation for the Synthesis of High‐Entropy Alloy Aerogels Toward H2O2 Production and Water Decolorization

Angewandte Chemie International Edition, EarlyView.
This work establishes a universal strategy for fabricating compositionally complex solid solution alloy aerogels via pulsed‐laser ablation and the sol‐gel process. The electrocatalytic capabilities of these aerogels are subsequently evaluated for H2O2 electrosynthesis and water treatment applications.
