Supercapacitive Performance of Ordered Mesoporous Carbon (CMK-3) in Neutral Aqueous Electrolyte
Ordered Mesoporous Carbon (OMC) represents an interesting material for electric double layer capacitors which has the high surface area, easily accessed ordered pore channels and lower production cost. In this work, CMK-3 as promising OMC has been fabricated using the ordered mesoporous silica SBA-15 as a template. The structure and morphology of CMK-3 are characterized by X-ray diffraction...
متن کاملAdditive-Driven Self-Assembly of Well-Ordered Mesoporous Carbon/ Iron Oxide Nanoparticle Composites for Supercapacitors
Ordered mesoporous carbon/iron oxide composites were prepared by cooperative self-assembly of poly(tbutyl acrylate)-block-polyacrylonitrile (PtBA-b-PAN), which contains both a carbon precursor block and a porogen block, and phenol-functionalized iron oxide nanoparticles (NPs). Because of the selective hydrogen bonding between the phenol-functionalized iron oxide NPs and PAN, the NPs were prefer...

متن کاملInfluence of spatial configurations on electromagnetic interference shielding of ordered mesoporous carbon/ordered mesoporous silica/silica composites
Ordered mesoporous carbons (OMCs), obtained by nanocasting using ordered mesoporous silicas (OMSs) as hard templates, exhibit unique arrangements of ordered regular nanopore/nanowire mesostructures. Here, we used nanocasting combined with hot-pressing to prepare 10 wt% OMC/OMS/SiO2 ternary composites possessing various carbon mesostructure configurations of different dimensionalities (1D isolat...
