Recently, the glycolipids biosurfactant materials have widely been utilized for many industrial applications due to their feasible surface activity, biodegradable as well as eco-friendly nature. Even though many of the earlier studies have been reported on such kind of surfactants, in this study we focused on porous rocks-like Fe 2 O 3 /C composites, which were magnificently synthesized from a novel tropical fruit biomass, using a glycolipid biosurfactant with high specific surface area of about 466.9 m 2 /g via a biofunctional single-step thermochemical method. They could be applied as an adsorbent to adsorb the pharmaceutical pollutants mainly, DCF from aqueous solution. Moreover, the highest adsorption capacity for DCF could be achieved, which is of about 77.51 mg/g. Furthermore, as-prepared glycolipid functionalized Fe 2 O 3 /C composites were used as electrode materials for high-performance supercapacitors.Galvanostatic charge-discharge results showed that the Fe 2 O 3 /C modified electrode possesses a specific capacitance of about 374 F/g with a current density of 0.2 A/g and it has retained 84% of capacitance, even after 3000 cycles.
