Synthesis of magnesium oxide nanoparticles (MgO NPs) using Terminalia chebula seeds extract as fuel by solution combustion method and their applications have been reported in this study. Characterization of the synthesized MgO NPs via Powder XRD, FT-IR, SEM, TEM and EDAX for structural and morphological studies was carried out. MgO NPs were used as a catalyst for production of biodiesel from used cooking oil and for the synthesis of selenoesters. The selenoesters were analyzed by mass spectrometry, 1H NMR, 13C NMR, FTIR techniques and the antifungal activity was investigated for some of the selenoesters against two pathogenic strains F. oxysporum and A. niger with Fluconazole as a standard drug. Biodiesel produced was tested for conformity with the ASTM standard and the results are reported herein. This is one of the novel methods reported for the synthesis of MgO NPs using terminalia chebula seeds, which are easily available, non-toxic, make the NPs green. Catalytic performance of these MgO NPs can be explored further for the synthesis of other organic compounds.
