홈페이지논문 초록 (Abstract)
The authors report the simple and easy method to fabricate transition-me tal-carbon nanotube hybrid materials through nitrogen mediation. Ni nano particles were uniformly dispersed on carbon nanotubes without any pretr eatment such as defect activation by strong acids or covalent functional ization processes. A theoretical study of the nitrogen-mediated mechanis m using first-principles density functional theory calculations is also presented. The first-principles calculations reveal that pyridinelike n itrogen incarbon nanotubes significantly enhances the binding energy of Ni interacting with carbon nanotubes.
