采用喷雾热解法制备了亚微米级氮化硼(BN)/碳纳米管(CNT)复合粒子。利用超声波雾化器，将纳米氮化硼、二茂铁(催化剂)和乙醇(作为溶剂和碳源)喷入管式炉(固定温度为800℃)中，气体流量为i L/min。乙醇因其无污染、低成本、无害的副产物(如一氧化碳)和易于处理而被用作溶剂和碳源。在纳米碳管表面可以生长出厚度为10 nm的多壁碳纳米管，形成聚集态的BN颗粒。由于该过程在几秒钟内完成，因此没有改变BN阶段。这种新的合成方法可以简单、快速、连续地在颗粒表面生长碳纳米管，从而广泛应用于各种复合材料的制备。(C)2009爱思唯尔B.V.保留所有权利。
Boron nitride (BN)/carbon nanotube (CNT) composite particles in submicrometer-sizes were successfully prepared using a spray pyrolysis method. Using an ultrasonic nebulizer, BN nanoparticles, ferrocene (as catalyst), and ethanol (as solvent and carbon source) were sprayed into a tubular furnace (fixed temperature of 800 degrees C) under an Argon flow of I L/min. Ethanol was used as a solvent as well as a carbon source because of its non-polluting nature, low cost, harmless byproducts (e.g. CO), and ease of handling. An aggregated BN particle with the growth of a multiwall-CNT (10 nm in thickness) on the surface could be produced. No BN phase changed because the process was completed in a matter of seconds. The present novel synthesis method could be broadly applied in the fabrication of various composite materials with the growth of CNT on the particle surface using a simple, fast and continuous process.
