Synthesis of mesoporous carbon material by hard template method: a comparative study of SBA-15 and MCF as templates
Abstract
Ordered mesoporous carbons (OMC) have been synthesized using mesoporous silica of SBA-15 (Santa Barbara Acid-15) and MCF (Mesoporous cellular foam) as hard templates. The synthesized carbon materials were characterized by different techniques such as the powder X-ray diffraction, transmission electron microscopy, N2 adsorption–desorption measurements. From obtained results, it revealed that the average pore width of OMC(MCF) samples (5.7 nm) was higher than that of OMC(SBA-15) samples (4.5 nm). OMC samples also exhibited high Methylene Blue (MB) adsorption capacity with Qmax of 385 mg/g for OMC(SBA-15) and 625 mg/g for OMC(MCF). The mesoporous silica template allows controlling the textural properties, providing new possibilities for many applications in adsorption and catalysis.
