    This research aims to conduct a thorough analysis of the novel and cost-effective use of Ipomoea cairica L. seeds as a potential feedstock for green energy technologies. Ipomoea cairica L. seeds (42 % oil, 0.67 % free fatty acid content) were used as a promising source for producing sustainable biodiesel using novel green Molybdenum Oxide (MoO3) nanocatalyst. The Ipomoea cairica seeds utilized in this study serve a dual purpose: they provide feedstock for the future energy mix, and their seed shells (considered waste) are used as a starting material for synthesizing green nanocatalysts. The highest biodiesel yield of 95 % was achieved under optimal reaction conditions of 1:15 oil to methanol molar ratio, 50 °C, 120 min, and 0.4 (wt.%) catalyst loading. In order to evaluate the quality and characteristics of the resultant biodiesel and synthesized nanocatalyst, a detailed examination was conducted utilizing analytical techniques such EDX, XRD, FTIR, SEM, NMR (1H, 13C) and GC–MS analysis. The phytofabricated nanocatalyst unveils highest recyclability (up to 5 cycles), reactivity, stability and efficiency during transesterification operations. The produced biodiesel was also optimized using response surface methodology (Box-Behnken Design). When compared to conventional diesel, the biodiesel made from Ipomoea cairica L. seed oil showed better oxidative stability and reduced viscosity, suggesting that it might be a viable replacement for conventional fuel without compromising engine performance. Moreover, using untamed, uncultivated, and non-edible seed plants to produce biodiesel presents a chance to move toward a more sustainable and environmentally friendly energy plan.
