Metal salts of carboxylic multiwalled carbon nanotubes – preparation, structure and thermal properties

Abstract

Salts of carboxylated multiwalled carbon nanotubes with monovalent Ag(I), Li, Na, NH4, divalent Ba, Co(II), Cu(II), Pd(II), UO₂, Zn, trivalent Ce(III), Cr(III), In(III), Ru(III), Sm(III), tetravalent Pt(IV), Th(IV) and pentavalent Nb(V) cations were prepared and elucidation of their structure was attempted based on their thermal and the QMS analyses. The salts usually decomposed specifically up to 400 °C. Above that temperature decomposition of the nanotubes matter can proceed with either oxidizing or catalyzing participation of the metal derivatives formed on the thermolysis of the metal salts.
