One-pot synthesis of mesoporous carbons using phloroglucinol-formaldehyde and copolymer F127

Ordered mesoporous carbons(OMC) were synthesized by an organic-organic self-assembly method using phloroglucinol-formaldehyde as carbon precursor and triblock copolymer F127 as template.The effects of several synthetic parameters,such as polarity of water-ethanol mixed solvent and reaction temperature,the textural properties of the synthesized OMC were systematically investigated in combination with the characterization by N2 adsorption-desorption and low-angle XRD techniques.The results showed that when the mixture solvent with a high molar proportion of ethanol was used in the synthesis system,the synthesized materials had large pore sizes and volumes with a high degree of mesopore-structure ordering.However,when the mixture solvent with a low molar proportion of ethanol was used,the pore sizes and volumes,mesoporosity,and degrees of mesopore-structure ordering of the synthesized samples were reduced to some extent.When pure ethanol or ethanol-water mixture was used as solvent,increasing synthesis temperature could decrease the BET surface area,pore size and volume but enlarge the microporosity of the synthesized materials,and temperature effect was more pronounced when synthesized in the mixture solvent.
