Bio-derived three-dimensional hierarchical carbon-graphene-TiO 2 as electrode for supercapacitors.
TL;DR: A novel loofah-derived hierarchical scaffold to obtain three-dimensional biocarbon-graphene- TiO2 (BC-G-TiO2) composite materials as electrodes for supercapacitors and the synergistic effects of the naturally hierarchicalBiocarbon structure, graphene, and TiO 2 nanoparticles on the electrochemical properties are analyzed.
