采用一种以尿素为氮源的简单方法，在碳纤维、多壁碳纳米管和无机纳米线上进行氮化硼涂层。这一过程包括在H3BO3和尿素的混合物中加热碳纤维和纳米管或无机纳米线，然后在N-2气氛中进行1000摄氏度的热处理。我们已经能够用透射电子显微镜和X射线光电子能谱来表征BN涂层。尿素分解法为在一维纳米结构上包覆氮化硼提供了一种简单的方法。(C)2007 Elsevier B.V.保留所有权利。
A simple route involving urea as the nitrogen source has been employed to carry out boron nitride coating on carbon fibers, multi-walled carbon nanotubes and inorganic nanowires. The process involves heating the carbon fibers and nanotubes or inorganic nanowires in a mixture of H3BO3 and urea, followed by a heat treatment at 1000 degrees C in a N-2 atmosphere. We have been able to characterize the BN coating by transmission electron microscopy as well as X-ray photoelectron spectroscopy. The urea decomposition route affords a simple method to coat boron nitride on one-dimensional nanostructures. (C) 2007 Elsevier B.V. All rights reserved.
