Abstract

A highly regenerative multifunctional nanobot system, using Fe₃O₄@SiO₂@MgFe-LDH nanoparticles, is developed for efficient removal of waterborne azo dyes and pharmaceuticals. Efficient capture of pollutants, powerful Fenton degradation, and superior materials regeneration lead to a simple and cost-effective wastewater remediation solution.
