Abstract

Boron nitride, known as "white graphene", have attracted extensive attention to the fields of adsorption, catalysis and hydrogen storage due to their excellent chemical properties. In this paper, the phosphorus doped boron nitride material (P-BN), was successfully prepared by red phosphorus as a dopant for the preparation of porous boron nitride precursors, the phosphorus content in P-BN was adjusted by the addition rate of phosphorus. The tendency of specific surface area of P-BN increased firstly and then decreased with the increasing of phosphorus addition rate, and the maximum specific surface area was 837.08m2/g when the phosphorus addition rate was 0.50. The P-BN, prepared by the experimental, used as an adsorbent had been proved its adsorption capacity for heavy metal flue gas. In particular, P-BN had a stronger adsorption selectivity for Zinc compared with other heavy metals, and the adsorption capacity of P-BN for Zinc reached 5~38 times higher than that of other heavy metals. However, the maximum adsorption capacities of P-BN for Zinc and Copper in the single heavy metal atmosphere were 69.45mg/g and 53.80mg/g, respectively.
