Abstract
Developing advanced sorbent materials for effective removal of organic pollutants from water is of critical importance for environmental and water source protection. Here we reported the facile synthesis of hexagonal boron nitride (h-BN) fibers for efficient removal of methylene blue (MB) from water. The h-BN fibers was prepared by a combined sol–gel and temperature-controlled pyrolysis procedure in a N2 atmosphere, using boron acid and melamine as the precursors. The as-prepared fibers showed long fibrous morphology (from several to tens of micrometers), high specific surface area (∼627m2/g), mesoporous (3–4nm) structure. Benefiting from these advantageous features, the resulting h-BN fibers exhibited a fast adsorption rate for MB (C/C0
