Abstract
- In this paper, a novel low dimensional boron nitride nanoribbons (BNNRs) aerogels were successfully developed by a cost-effective, catalyst-free chemical vapor deposition using Boric acid and Melamine as the B and N sources. The obtained BNNRs aerogels were possessed porous structure (average pore diameter: 2 nm) and the width of a single nanoribbon was approximately 200 nm and large aspect ratio more than 50 times and the BET surface area of 530 m2/g approximately. Attractively, BNNRs aerogels exhibited an excellent adsorption capacity for both PEDOT: PSS (3, 4-ethylenedioxyethiophene: polystyrene sulfonate) (6020 mg/g) and mustard seed oil (5010 mg/g). The adsorbed BNNRs aerogels can be cleaned and reused by burning them in the air and they create favorable conditions for recycling. After comparison, our experimental study found that after two test cycles, the adsorption ratio of BNNRs aerogels to mustard seed oil was 261.28%, which was only 6.97% less than that of the first adsorption with 280.87%. After the 4 combustion-adsorption cycles, the aerogels also maintained a 105.53% adsorption ratio, which confirmed the ability of BNNRs aerogels to adsorb oil. Therefore, BNNRs aerogels material is a promising nanomaterial for environmental remediation and selective water purification and treatment.
