Carbon nanotubes (CNTs) were chemically modified by a series of binuclear hexamino-metallo (M2Pc2) which were produced by reducing the corresponding binuclear hexanitro-metallophthalocyanines (M(2)HnPc(2)) (M = Mn(II), Fe(II), Co(II), Ni(II), Cu(II), Zn(ll)). The compounds were characterized with different techniques: IR, UV-vis, XRD, SEM, XPS. The electrocatalytic performances of the CNTs bonding with M2Pc2 (M2Pc2-CNTs) to Li/ SOCl2 battery was tested by adding these compounds into the electrolyte. The capacities of the battery were improved, with increases by 59.1-128.5%. In addition, sequence of the electrochemical catalytic performance of M2Pc2-CNTs is as follow: Fe> Co> Cu> Zn > Ni > Mn. The CNTs bonding with M2Pc2 can greatly promote the electronic transmission, which significantly improve the performance and the initial voltage of Li/SOCl2 battery. Cyclic voltammetry measurements are applied to verify the M2Pc2-CNTs possessing catalytic performances and a reasonable mechanism is proposed. (C) 2017 Published by Elsevier B.V.
