Abstract

Electrochemical oxidations of complex toxic dyes have been widely investigated on metal–organic-framework, which are often limited by high energy demand or deactivation of organic support. Here, the potential application of a magnetically retrievable solar-driven nanocomposite of Nb2O5-CoFe2O4 for removing crystal violet was explored and compared under simulated solar radiation (60.82 mW/cm2) or darkness. In the synthesized composite, Nb2O5 exists as a dispersed phase on CoFe2O4, forming a core–shell structure. Both the optical and magnetic behaviour of Nb2O5-CoFe2O4 were extensively investigated to optimize their photocatalytic applications in the removal of crystal violet. The nanocomposite was strongly ferromagnetic even after loading Nb2O5 on cobalt ferrite. The photocatalytic performance of the composites showed a positive relationship with the Nb2O5 content, where optimum degradation was observed with 50 % Nb2O5-CoFe2O4. The ferromagnetic property was exploited to retrieve the catalyst from the water after the purification process. This study demonstrates the facile method for the novel Nb2O5-CoFe2O4 synthesis and elucidates its high potential in sustainable remediation of complex toxic dyes using solar energy and as reusable magnetic recovery in aqueous systems. Also, 50 % Nb2O5-CoFe2O4 has been implemented in water purification processes and pollutant degradation, thereby definitely amplifying the prospects for sustainable development of this research work. © 2024
