A Facile Synthesis of Carbon Nanobelts over Mo/Fe/MgO Catalysts

摘要

Carbon nanobelts(CNBs) with high purities (over 90％) have been successfully synthesized by catalytic decomposition of CH4 over Mo/Fe/MgO catalysts at 1173 K.The CNBs have thickness of about 8.0nm,width of about 50-200nm.with few defects and amorphous.It has been found that the addition of component Mo in catalysts plays a key role to synthesize the carbon nanobelts at high yields.The graphitic sheets increased with the increase of Mo content in catalysts.
