Multiwalled carbon nanotube (MWCNT)‐templated cobalt phthalocyanine (CoPc) assemblies are prepared by microwave reaction with the aid of NH 4 Cl. The assemblies of CoPc/MWCNTs are added to the electrolyte of Li/SOCl 2 battery to show their potential application in the field of catalysis. The assemblies display a uniform coaxial nanotube structure. In the control test, the CoPc/MWCNTs synthesized without NH 4 Cl exhibit the aggregation of the nanotubes of CoPc/MWCNTs. It indicates that the use of NH 4 Cl as gas source is efficient in enhancing diffusion of the MWCNTs and controlling the growth of CoPc. The catalytic reduction of SOCl 2 can be carried out by CoPc molecules outside the assemblies and the MWCNTs inside the assemblies. The assemblies of CoPc/ MWCNTs exhibit excellent electrochemical catalytic activity to Li/SOCl 2 battery. The discharge energy of Li/SOCl 2 battery catalyzed by CoPc/MWCNTs is 144% higher than that of the battery without catalyst, and is 94% higher than the energy of Li/SOCl 2 battery catalyzed by bulk CoPc.
