Using biomass-based catalysts in biodiesel production can make the process more economical and environmentally friendly. In this study, a new magnetic nanocatalyst was developed using banana peel biochar, ZIF-67, Fe3O4, K2CO3, then utilized catalytic transesterification to convert waste cooking oils (WCO) into biodiesel. The level of free fatty acids treated WCO (WCOT) reduced generate with suitable characteristics. physicochemical aspects were characterized by Fourier-transform infrared spectroscopy (FTIR), vibrating sample magnetometer (VSM), X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive (EDX) map techniques. process, effect temperature, methanol-to-oil ratio, time, weight on potential produce from WCOT explored. highest yield (96.82%) (99.18%) attained at 65 °C, 3 wt %, ratio 19:1, processing time h, mixing rate 600 rpm. Based thermodynamic studies, endothermic non-spontaneous. regeneration studied various solvents n-hexane had good ability recover catalyst (90% up 5 stages). results 1H NMR test revealed that desired high WCOT. properties produced met ASTM D6751 EN 14214 standards.
