Novel Thermal Decomposition Method for the Synthesis of Iron‐doped SnS2 Nanoparticles and Studies on their Peroxidase‐like Activity

Abstract

AbstractIron‐doped SnS2 nanoparticles (Sn1‐xFexS2) have been synthesized by a novel thermal decomposition method. Phase analysis was done using powder XRD. FE‐SEM and TEM studies show flake‐like morphology for iron doped SnS2 nanoparticles. Diffuse reflectance spectroscopy results demonstrate blue shift of band gap of Sn1‐xFexS2 nanoparticles with respect to pure SnS2 nanoparticles. M−H measurements of iron doped SnS2 nanoparticles at 300 K and 2 K show weak ferromagnetic behaviour when x=0.10 and 0.15. When x=0.20, paramagnetic behaviour at 300 K and superparamagnetic behaviour at 2 K are observed. ZFC‐FC measurements were also carried out for the iron doped SnS2 nanoparticles. The Sn1‐xFexS2 nanoparticles were used as catalyst for peroxidase‐like activity and for the detection of H2O2.
