Multiwall carbon nanotube@mesoporous carbon with core-shell configuration: a well-designed composite-structure toward electrochemical capacitor application†
Abstract
Based on the desired electrical conductivity and high specific-surface-area for carbon-based electrodes, herein, we have designed and synthesized uniform multiwall carbon nanotube@mesoporous carbon (MWNT@mesoC) composites with core-shell configuration by combining sol–gel methods and nanocasting. Pristine MWNTs after acid treatment were first coated with uniform mesostructured
