제목 3-D ordered bimodal porous carbon/nickel oxide hybrid electrodes for supercapacitors
초록 Supercapacitors have attracted attention owing to their high power capabilities in energy storage system. However, the energy density of supercapacitors is lower than that of batteries. In this study, in order to enhance the energy density of supercapcity, 3D-ordered bimodal porous carbons were fabricated, containing macropores and a large amount of sub-/nanometer pores (micropores) with narrow pore size distribution. Nickel oxide nanoparticles of 2–4 nm were introduced on this bimodal porous carbon. The bimodal porous carbon/NiO nanoparticle hybrid exhibited better electrochemical performance than that of 3D-ordered macroporous carbon/NiO nanoparticle hybrid, because of the synergistic effects from the electric double-layer capacitance of a large amount of micropores, enhanced wettability due to oxygen heteroatoms introduced from the activation process, and pseudocapacitive redox reactions of NiO nanoparticles.
