Facile synthesis of magnetic and porous zeolite/SnFe2O4 nanocomposite for cationic and anionic dyes deterioration

This study introduces a new, accessible, and cost-effective nanocatalyst for wastewater remediation. Here, tin ferrite nanoparticles (SnFe2O4) were loaded onto the surface of zeolite using a one-step solvothermal method. The characteristics of the zeolite/SnFe2O4 nanocomposite were thoroughly investigated using a range of techniques including SEM, EDX, VSM, XRD, TEM, BET, and FTIR. The nanocomposite was used as a heterogeneous catalyst along with H2O2 (a green oxidant) to degrade cationic (methyl green) and anionic (methyl blue) dyes in both individual and mixed systems. The amounts of zeolite/SnFe2O4, H2O2, and dyes substantially affected the degradation rate. Moreover, as the pH rose, both dyes deteriorated at a faster rate. The magnetic nanocomposite demonstrated exceptional separation and regeneration performance throughout 5 cycles. Moreover, when the two dyes were combined into a single solution, the nanocomposite showed a significant removal ability, indicating a potential benefit in wastewater treatment.
