Abstract
Carbon with mesopores (about two to fifteen nanometers in average pore size) is made using sucrose as a source of carbon, and silica and phosphoric acid as templates for the mesopore structure in the carbon. A silica sol is prepared in a water/ethanol medium and sucrose is dispersed in the sol. Phosphoric acid may be added to the sol to control pore size in the mesopore size range. The sol is dried, carbonized, and the silica and phosphate materials removed by leaching. The residue is a mesoporous carbon mass having utility as a catalyst support, gas absorbent, and the like.
