Chemistry of zipping reactions in mesoporous carbon consisting of minimally stacked graphene layers

Abstract

The structural evolution of highly mesoporous templated carbons is examined from temperatures of 1173 to 2873 K to elucidate the optimal conditions for facilitating graphene-zipping reactions whilst minimizing graphene stacking...

Extraordinary Capacitance and Stability of Carbon Electrode for Electrochemical Capacitors

“…48,51 Following the template removal under conditions that prevent additional stacking, 52 edge sites are removed via zipping reactions occurring at temperatures exceeding 1600 °C. 53 GMS possesses developed mesoporosity, a high specific surface area (³2000 m 2 g ¹1 ), excellent conductivity, and high oxidation resistance, 45,54 all of which align with the characteristics anticipated in structures like carbon schwarzites composed of edge-free and minimally stacked graphene framework. Moreover, GMS exhibits a distinctive elasticity that makes it further apart from other nanoporous carbon materials, opening up new possibilities for innovative applications utilizing mechanical deformation.…”

Synthesis of nitrogen-doped carbon nanoboxes with pore structure derived from zeolite and their excellent performance in capacitive deionization

“…The conductivities of densely compacted HCNBs samples were also measured and displayed in Table S2 †. The conductivities were similar to those of other porous carbon materials 47 (2–10 S cm −1 ), so in this work, additional conductive agent, i.e. , carbon black was added for HCNBs once used as electrode materials in capacitance measurement.…”

Toward three-dimensionally ordered nanoporous graphene materials: template synthesis, structure, and applications

“…Nanosized γ-alumina is a promising template material for synthesizing nanoporous graphene (NPG) materials since it is one of the most efficient catalysts for catalytic C–H activation. 89 CH 4 -CVD takes place on alumina nanoparticles (ANPs) with the initial associative dissociation of CH 4 as the kinetic bottleneck, 59 and this is followed by acid etching and annealing 86,90–93 to give NPGs as minimally stacked porous graphene analogs (Fig. 2).…”
