Waste Toner-Derived Carbon/Fe₃O₄ Nanocomposite for High-Performance Supercapacitor.

ABSTRACT: Electronic waste management is one of the key challenges for the green revolution without affecting the environment. The wide use of printer devices has brought a horde of discarded waste toner, which release ∼6000 tons of processed carbon powder into the atmosphere every year that would essentially pollute the atmosphere. Here, we propose a one-step thermal conversion of waste toner powder into carbon/Fe₃O₄ nanocomposites for energy storage applications. Recovered toner carbon (RTC) and toner carbon calcined at 300 °C (RTC-300) were characterized using various analytical tools. From the FE-SEM analysis, the presence of carbon particles with uniformly decorated Fe₃O₄ nanoparticles was confirmed. RTC-300 carbon was used as an electrode material fo
