Customizable Three-Dimensional Printed Zerovalent Iron: An Efficient and Reusable Fenton-like Reagent for Florfenicol Degradation.

ABSTRACT: Zerovalent iron (Fe⁰)-based Fenton-like technology has great potential for treating recalcitrant organic pollutants (ROPs) in wastewater. However, rapidly and precisely manufacturing Fe⁰-based materials with the desired geometries is challenging. Herein, novel three-dimensional printed Fe⁰ (3DP-Fe⁰) and bimetallic 3DP-Ni/Fe⁰ were customized by 3D printing for efficient Fenton-like degradation of florfenicol (FLO), a typical antibiotic in wastewater. 3DP-Ni/Fe⁰ with hydrogen peroxide (H₂O₂) exhibited superior reactivity toward FLO than 3DP-Fe⁰, generating hydroxyl radicals (·OH) and atomic hydrogen to achieve >90% dehalogenation and >70% total organic carbon removal within 10 min.
