Boron was introduced into carbon papers (CPs) to catalyze their graphitization in this paper. The results showed the graphitization of CPs was moved from 2400 degrees C to 2100 degrees C. At 2100 degrees C, boron substituted carbon atoms in the hexagonal carbon lattices to form a solid solution, and the catalytic mechanism was dissolution and precipitation. CPs with excellent electrical conductivity and good permeability were prepared at lower temperature. Thus, the boron-doping method provides a new way to prepare high performance CPs at lower costs.
