Study of the mesopore size effect on the electrochemical capacitor behaviors of mesoporous carbon/quinone derivative hybrids

A quinone derivative, 2,5-dichloro-1,4-benzoquinone (DCBQ), is hybridized with MgO-templated mesoporous carbons (MgO-Cs) with the average pore sizes of 5, 10, and 30 nm through gas-phase adsorption. The resulting hybrids are used for aqueous electrochemical capacitor electrodes due to the reversible redox reaction of DCBQ within the mesopores when using an aqueous H2SO4 electrolyte. This hybridization method precisely controls the weight ratio...
