中文摘要：
介绍了一种大规模制备形貌可控的中空纳米炭材料的方法。该方法以金属氧化物为模板,利用乙苯分子在金属氧化物表面高温快速产生的积炭为炭源,除去模板后可以得到具有中空结构的纳米炭材料。该方法简单、高效、低成本,具有普适性,制备过程中不需要使用昂贵的表面活性剂为炭源。利用该方法,以实验室制备的氧化锌纳米棒和商业的氧化锌纳米球为模板,分别成功的制备出中空纳米炭管和中空的纳米炭球。该合成方法可以进一步推广到制备其它形貌的中空纳米炭材料并用于催化和能量储存等领域。
英文摘要：
A ZnO template approach for the large scale synthesis of hollow carbon nanostructures was developed. A diluted ethyl- benzene stream was used to form a carbon layer on the template at a high temperature and a dilute HC1 solution was used to etch the template. Hollow carbon nanotubes and hollow carbon nanospheres were fabricated using ZnO nanorods and nanospheres as the re- spective templates. The present process is simple, efficient and low cost, and may be extended to fabricate other hollow carbon nanostructures used in catalytic reactions and energy storage.
