Synthesis of ordered mesoporous carbon using m-Diethynylbenzene as a new precursor

Abstract

m-Diethynylbenzene (m-DEB) was used for the first time as a precursor in the synthesis of mesoporous carbons(OMCs) via the wet infiltration method. The results from X-Ray powder diffraction, Transmission electron microscopy, N2 adsorption-desorption isotherms and TGA curves confirmed that after carbonization at 800°C, 1000°C, 1200°C and removal of the template, OMCs with very narrow pore size distributions (centered at about 4nm), high order and relative high thermal stability(as high as 600°C for OMC-800) were obtained. This work provided a facile way to prepare ordered mesoporous carbon materials with relative high thermal stability.
