Construction of cobalt–nickel bimetallic coordination polymers and their catalytic thermal decomposition of ammonium perchlorate.

Bimetallic complexe Ni-Co-pzdc and its derivatives were prepared by a simple method, both were used to catalyze ammonium perchlorate to improve its thermal decomposition performance, and the experimental results showed that all had good catalytic effects, among which, Ni-Co-pzdc derivatives had a more excellent catalytic effect, which made the high-temperature thermal decomposition temperature of AP lowered by 136 ℃ and the activation energy lowered by 128.21 kJ·mol−1. [Display omitted] • A novel bimetallic complex was prepared using 2,3-pyrazinedicarboxylic acid as a ligand and Ni and Co as the center metals. • Used the complex as a sacrificial template to obtain its derivatives as N-doped NiCoO 2 composite carbon materials. • The bimetallic oxide NiCoO 2 has a synergistic effect of metal ions, and the N-doped carbon material can accelerate the transfer of electrons and thus enhance the effect of catalytic AP, so the resulting derivatives have excellent catalytic properties. The addition of a catalyst to ammonium perchlorate (AP) can effectively improve its thermal decomposition properties. The heterobimetallic complex Ni-Co-pzdc (2,3-pyrazinedicarboxylic acid) was synthesized via in situ substitution, and the N-doped Ni-Co-pzdc derivative was prepared by using it as a sacrificial template. A series of characterization tools were used to investigate the morphological and structural features of the resulting materials, and the thermal decomposition behaviors of the two products were investigated by homogeneous mixing with AP, respectively, and the activation energies were calculated by using Kissinger, Kissinger-Akahira-Sunose (KAS), and Flynn-Wall-Ozawa (FWO), and the results showed that both substances possessed excellent catalytic activities.
