Biodiesel production from non-edible seed oils provides striking solution to the problems associated with the energy crisis. In this study, the potential of Citrus medica as a novel and non-edible seed oil (33% w/w) producing feedstock was investigated for biodiesel production using green and recyclable nanoparticles (NPs) of copper oxide synthesized with aqueous leaf extract of Portulaca oleracea. Green NPs of copper oxide were characterized by advanced techniques like X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), and Energy Diffraction X-Ray (EDX). A maximum yield of 93% of methyl ester was achieved at the optimum reaction condition of methanol to oil ratio 8:1, catalyst loading 0.18 wt%, reaction time 120 min and temperature 85 ?C. Both Fourier-transform infrared spectroscopy (FTIR) and nuclear magnetic resonance of biodiesel confirmed the presence of methyl ester in the synthesized biodiesel sample. Five distinct peaks of methyl esters were identified in biodiesel by gas chromatography-mass spectrometry (GC�MS) analysis. Fuel properties of methyl esters were investigated and found analogous to the international standards. The results indicated that Citrus medica is a potential, environmentally friendly biomass feedstock for renewable production of biodiesel using green NPs of copper oxide as catalyst. � 2022 Elsevier Ltd Final 2023-05-29T09:36:38Z 2023-05-29T09:36:38Z 2022 Article 10.1016/j.fuel.2022.124285 2-s2.0-85129122676 https://www.scopus.com/inward/record.uri?eid=2-s2.0-85129122676&doi=10.1016%2fj.fuel.2022.124285&partnerID=40&md5=be29d5a8b4dadfbda125995761864b1b https://irepository.uniten.edu.my/handle/123456789/26778 323 124285 Elsevier Ltd Scopus |
