Preparation and Characterization of Mesoporous Carbon Materials Based on Hard Coal-Tar Pitch

Abstract:

Mesoporous carbons were prepared by one step method using hard coal pitch as carbon source, in which magnesium oxide was adopted as template. The adsorption value of vitamin B₁₂, specific surface and pore size distribution, surface topography of mesoporous carbons were tested by spectrophotometer, specific surface analyzer and scanning electron microscopy. The results showed that the vitamin B₁₂ absorption value on mesoporous carbon could be improved with suitable carbonization temperature and mass ratio of template agent to carbon source. The maximum value achieved to 103.82mg/g when the mass ratio of MgO to modified pitch was 8:2.
