Study Findings from University of Nantes Provide New Insights into Fullerenes

February 7, 2014

By a News Reporter-Staff News Editor at Science Letter -- Research findings on Fullerenes are discussed in a new report. According to news reporting originating from Nantes, France, by NewsRx correspondents, research stated, "This research treats a particularly challenging undertaking in carbon nanoscience: controlling the diameter distribution of single walled carbon nanotubes (SWCNTs) grown using CVD. To do so requires the fabrication of well-separated and monodispersed catalytic metal nanoparticles which can be uniformly distributed on a substrate."

Our news editors obtained a quote from the research from the University of Nantes, "We propose a new strategy involving the preparation of a monolayer of chemisorbed nickel acetylacetonate which is shown by infrared spectroscopy and coupled thermogravimetric-mass spectrometry analyses to be anchored to the surface silanol groups of the substrate. After decomposition of this precursor, the nickel remains bonded with these surface silanol groups which upon further heating results in good dispersion of the nanoparticles over the silica surface. Using this catalyst, SWCNTs with a very discrete chiral preference and a narrow diameter distribution were synthesized at moderate temperature."

According to the news editors, the research concluded: "This work thus opens new perspectives for the fabrication of uniform-diameter carbon nanotubes."
