Carbon nanotubes (CNTs) of narrow size distribution can be abundantly produced in the catalytic decomposition of CH₄ over pre-reduced LaNiO₃, La₄Ni₃O₁₀, La₃Ni₂O₇ and La₂NiO₄.The CNTs obtained were characterized by means of transmission electron microscopy (TEM).Thermal oxidation of CNTs in air was monitored thermogravimetrically (TG). The resultsrevealed that a lower La/Ni ratio of the catalysts would lead to a wider diameter distribution and a higher degree of graphitic nature.
