英文摘要Zerovalent iron (Fe-0)-based Fenton-like technology has great potential for treating recalcitrant organic pollutants (ROPs) in wastewater. However, rapidly and precisely manufacturing Fe-0-based materials with the desired geometries is challenging. Herein, novel three-dimensional printed Fe-0 (3DP-Fe-0) and bimetallic 3DP-Ni/Fe-0 were customized by 3D printing for efficient Fenton-like degradation of florfenicol (FLO), a typical antibiotic in wastewater. 3DP-Ni/Fe-0 with hydrogen peroxide (H2O2) exhibited superior reactivity toward FLO than 3DP-Fe-0, generating hydroxyl radicals (OH) and atomic hydrogen to achieve >90% dehalogenation and >70% total organic carbon removal within 10 min. The resulting degradation intermediates possessed lower antibacterial activity than FLO and did not cause resistance gene proliferation in activated sludge. The Fenton-like activity of 3DP-Ni/Fe-0 was similar across different shapes but increased with increasing porosity and size. Compared with powdered Ni/Fe-0, 3DP-Ni/Fe-0 exhibited faster electron transfer during Fe(II)/Fe(III) cycling, which increased the utilization efficiency of dissolved Fe2+ and H2O2 for OH production. Moreover, 3DP-Ni/Fe-0 could be reused >150 times, 5-fold more than powdered Ni/Fe-0, owing to its lower metal ion release and Fe-0 depletion. 3DP-Ni/Fe-0 with H2O2 can also efficiently remove chemical oxygen demand from real wastewater and other ROPs (e.g., acetaminophen, carbamazepine, thiamphenicol, and tetrabromobisphenol A).
