Low-temperature synthesis of ordered graphite nanofibres using nickel(ii)-exchanged zeolites

Abstract

Ordered graphite nanofibre formation has been observed at exceptionally low temperatures on admission of ethyne to zeolite Y, which had been exchanged with Ni(II). The samples have been characterised by TEM, carbon analysis, and electronic spectroscopy. Formation of the nanofibres requires no hydrogen, and was not observed when cation exchange was carried out at acidic pH. The observed fibres resemble herring-bone nanofibrils, growing from nickel particles, and ca. 90% have diameters in the range 35–40 nm. Similar fibres have also been grown using nickel-exchanged zeolite β.
