| Outline of Final Research Achievements |
Hierarchically porous resorcinol-formaldehyde gels comprising mesoporous nanorod assemblies with two-dimensional hexagonal ordering by combining a supramolecular self-assembly strategy and phase separation in micrometer-scale. The new post-treatment method to introduce heteroatoms (nitrogen, phosphorus, and sulfur) into carbon materials with high doping level has also been developed. In addition, the electrochemical investigation on the undoped and doped carbon monolithic electrodes applied to supercapacitors has provided insights into the effects of heteroatom doping on the electrochemical capacitance. Meanwhile, the hierarchically porous carbon monolith showed good electrochemical sodium storage behavior. It is found that the well-defined mesoporous structure is favorable for improving the rate capability.
