Production of boron-doped porous carbon by the reaction of carbon dioxide with sodium borohydride at atmospheric pressure

Abstract

Boron-doped porous carbon was produced from carbon dioxide (CO2) reaction with sodium borohydride at moderate conditions. The reaction was first investigated by using a combined thermogravity-differential scanning calorimeter, and then the transformation was carried out in a tubular reactor. Results demonstrated that, at temperatures below 500 degrees C, CO2 can be reduced to porous carbon under atmospheric pressure. The incorporation of boron atoms into the carbon lattice was confirmed by using X-ray photoelectron spectroscopy. (C) 2012 Elsevier Ltd. All rights reserved.
