Herein, Ferric sulphide nanoparticles were prepared by co-precipitation (green synthesis) method.Structural study (XRD) confirms the crystalline nature of prepared Ferric sulphide nanoparticles. The crystallite size was estimated and it was found to ~2.0 nm. The surface morphology of the Fe2S3 nanoparticles shows the agglomeration and is sponge and dried algae like structure. EDS analysis reveals the presence of Fe, S, O and C elements in the prepared Ferric sulphide nanoparticles. FTIR spectrum of Ferric sulphide shows the characteristic peaks that confirms the presence of Fe and S in the sample. Moreover, the plant growth study proves that Ferric sulphide nanoparticles could be used as a fertilizer to enhance the agricultural production.

Potassium (K) doped ferric sulphide nanoparticles were prepared by a simple green synthesis (Bio-Assisted) method. Structural (XRD) studies confirm the formation of K-doped Ferric sulphide nanoparticles. The FESEM images show the agglomeration of nanoparticles that are mostly sponge like structure and spherical shape. The plant growth analysis revealed that potassium doped ferric sulphide nanoparticle could be used as plant growth promoter for high yield in agriculture.
