3D‐Printed Porous High‐Entropy Alloy Boosts Peroxymonosulfate Activation for Long‐Term Organic Pollutant Degradation

ABSTRACT High‐entropy alloys (HEAs) have attracted considerable interest from researchers owing to their tunable chemical compositions, exceptional structural stability, and promising catalytic properties. However, their large‐scale application is often hindered by complex manufacturing techniques and poor durability. Herein, we report a simple and cost‐effective three‐dimensional (3D) printing strategy to fabricate a 3D‐FeMnCrCo HEA catalyst with precisely controlled composition, structure, and porosity. The as‐prepared 3D‐FeMnCrCo catalyst exhibits high printing accuracy, excellent compression resistance, and remarkable efficiency in degrading organic contaminants using peroxymonosulfate (PMS) activation.…
