Binuclear metal phthalocyanines bonding with carbon nanotubes as catalyst for the Li/SOCl2 battery
Carbon nanotubes (CNTs) were chemically modified by a series of binuclear hexamino-metallo (M2Pc2) which were produced by reducing the corresponding binuclear hexanitro-metallophthalocyanines (M2HnPc2) (M=Mn(II), Fe(II), Co(II), Ni(II), Cu(II), Zn(II)). The compounds were characterized with differen...

Summary: | Carbon nanotubes (CNTs) were chemically modified by a series of binuclear hexamino-metallo (M2Pc2) which were produced by reducing the corresponding binuclear hexanitro-metallophthalocyanines (M2HnPc2) (M=Mn(II), Fe(II), Co(II), Ni(II), Cu(II), Zn(II)). 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.
•The M2Pc2-CNTs catalysts were synthesized byCNTs bonding with M2Pc2.•The capacity of the battery electrocatalyzed by Fe2Pc2-CNTs (linked) is 96.09Aˑh more than 128.5%•The synergistic effect between the CNTs and the binuclear phthalocyanine improve the capacity of the battery.•The catalytic mechanism of the battery catalyzed by binuclear metallophthalocyanine has been investigated. |
