A carbon microtube
aerogel (CMA) with hydrophobicity,
strong adsorption capacity, and superb recyclability was obtained
by a feasible approach with economical raw material, such as kapok
fiber. The CMA possesses a great adsorption capacity of 78–348
times its weight. Attributed to its outstanding thermal stability
and excellent mechanical properties, the CMA can be used for many
cycles of distillation, squeezing, and combustion without degradation,
which suggests a potential practical application in oil–water
separation. In addition, the adsorption capacity still retained 98%
by distillation, 97% by squeezing, and 90% by combustion after 10
cycles. Therefore, the obtained CMA has a broad prospect as an economical,
efficient, and environmentally friendly adsorbent.
