Synthesis of metal oxide nanomaterials using phytochemicals has now been regarded as mutually exclusive to chemical synthesis techniques. Here, we have extracted, isolated, and characterized the phytochemicals of Euphorbia cognata Boiss leaf hydro-organic extract and utilized them as biofuel in the preparation of metal oxide nanoparticles (CoO NPs). To evaluate the chemical composition of bio templates, chromatographic techniques like high-performance liquid chromatography (HPLC) and gas chromatography-mass spectroscopy (GC-MS) were being utilized. The reducing properties of the organic fuel were investigated by efficiently synthesizing CoO NPs by treating aqueous plant extract with an aqueous complex of Co(NO3)·6H2O. X-ray diffraction (XRD) was utilized for identification of newly prepared NPs, and composition of elements was inveterate via energy dispersive X-ray spectroscopy (EDX). The spherical-shaped morphology was noticed via field emission-scanning electron microscopy (FE-SEM), and the biocomponents of synthesized metal oxide were identified by GC-MS which has confirmed the active presence of monopolized octodrine, decanoic acid, cathinone, and acetic acid in the synthesized metal oxides NPs. Overall, the present study has demonstrated well the significant potential of E. cognata phytocompounds as fuel in the synthesis of nanomaterial.
