摘要

An all-in-one solvent! Hierarchical carbon-carbon nanotube composites were synthesized by using deep eutectic solvents (DESs) as reaction media, catalyst, and structure-directing agent. The resulting carbon monoliths exhibited a combination of high conductivity, hierarchical structure, and mechanical properties that contributed to retention of 75 % of the initial capacitance at current densities of up to 29 A g~(-1).
