Synthesis of porous boron nitride as an adsorbent for bisphenol A

The efficient removal of organic pollutants from waste water is important to minimize their detrimental effects on the environment. Advanced adsorbent materials need to be developed to address this problem. Boron nitride (BN) has long been known for its high thermal and chemical stability. It is only recently that porous boron nitride is attracting attention as an adsorbent for pollutants [1,2]. The formation of BN-layers occurs which consist of a hexagonal plane with boron and nitrogen atoms linked by sp2 hybridized orbitals. This hexagonal BN is able to interact with organic pollutants via pi-pi interaction in a similar way as graphene layers interact with aromatic organic compounds. The effect of ceramization temperature on the material characteristics of porous BN was investigated as well as their capability to remove BPA from water.
