An ordered hydrophobic P6mm mesoporous carbon with graphitic pore walls and its application in aqueous catalysis

Study of the adsorption mechanisms of ciprofloxacin antibiotics onto graphitic ordered mesoporous carbons

“…During the past decades, most of the mesoporous carbons fabricated was chosen as hard or soft template and amorphous carbon sources as carbon precursors lead to amorphous carbon-like nature matrix [19,20] , resulting in materials with inferior performances in particular mechanical stability and hydrophobicity compared to graphite carbon [21] . In addition, these materials are more efficient for adsorption if in graphitic form, while possess chemical durability, more mesoporous pore volume, corrosion resistance [22] .…”

Highly Ordered Mesoporous Few‐Layer Graphene Frameworks Enabled by Fe3O4 Nanocrystal Superlattices

“…Despite different pore widths,a ll the MGF samples exhibit al ong-range ordered fcc structure as indicated by the sharp scattering peaks,t hus suggesting that the variation of NC size does not affect the symmetry and structural ordering of the resulting MGFs.F igure 3c shows typical N 2 adsorption-desorption curves of MGFs derived from 12 nm Fe 3 O 4 NCs,which exhibit prominent characteristics of type-IV isotherms,w hile the large H 2 -type hysteresis loop at P/P 0 of about 0.47 implies acaged mesoporous structure with small openings on the pore walls, [17] similar to the case of OMCs ( Figure S4). [18] Because of their highly ordered and accessible mesopores, large surface area, and high electronic conductivity,the MGFs obtained are expected to be particularly suitable as anode materials for LIBs.The electrochemical performance of MGF anodes is evaluated by both cyclic voltammetry and galvanostatic charge-discharge cycling. These results suggest that the ultrathin pore walls of MGFs are interconnected to form a3Dcontinuous porous structure.The typical Brunauer-Emmett-Teller (BET) surface area of MGFs is about 1000 m 2 g À1 with ap ore volume of approximately 1.8 cm 3 g À1 .Notably,the BET surface area of MGFs is higher than that of many ordered graphitic mesoporous carbons reported previously.…”
