Abstract

Abstract:

Ammonium pentaborate, ammonia borane and magnesium oxide powder were ball milled and then heated at 1200 ℃ for 12 min in the atmosphere of 50 mL/min ammonia gas. And the white flocculent product was collected on the surface of the alumina substrate. The experimental results indicated that the samples revealed one-dimensional linear hierarchical structures with an average length of more than 5 mm and the outsider diameter of 200—800 nm. And the middle of the hierarchical structure was bamboo-like hollow structure with the inner diameter of 50—350 nm. In addition, abundant BN nanosheets loaded on the surface of the BNNT hierarchical structure and the thickness of single nanosheet was about 13 nm. Lots of nanosheets bended, folded and interweave together to form BN layer with the thickness of 50—200 nm. Besides, UV-Vis and PL analysis demonstrated that the as-synthesized BNNT hierarchical structures could be used in the field of ultraviolet light materials. The BNNT hierarchical structures also presented excellent adsorption property for methylene blue(MB). When the adsorption time was 7 min, MB was removed by 71% from water solution. The adsorption rate increased to 96% when the adsorption time was 107 min. Finally, the comparison experiment indicated that the growth mechanism of BNNT followed the vapour-liquid-solid(VLS) model, but the growth mechanism of the surface-loaded BN nanosheet belonged to vapour-solid(VS) model.
