ABSTRACT: Materials combining graphitic carbon with metal oxide nanoparticles are critical for applications in water treatment, catalysis, and energy storage. These composites leverage carbon's electrical conductivity and chemical resilience to enhance the catalytic, electronic, and magnetic properties of metal oxide nanoparticles. Previous approaches to synthesizing such materials have relied on high-temperature (>600 °C) pyrolysis of powders, a process that can alter nanoparticle size, composition, and morphology. Alternative lower-temperature routes in solution yield amorphous carbon, which lacks the conductivity and chemical resistance of graphitized carbon. This study presents a route to form graphitic carbon coatings on iron, manganese, and cobalt oxide nanoparticles at temperatures below 400
