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

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 °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.
