摘　　要：系统地总结了单核金属酞菁对锂/亚硫酰氯电池的催化性能。设计合成了8系列不同结构的单核酞菁化合物,研究了其作为催化剂对电池的催化性能。根据催化性能推测了金属酞菁作为锂/亚硫酰氯电池的催化机理。研究结果表明,大部分金属酞菁加入到电池中,电池容量都有较大程度的提高(提高15%～125%)。其中,MPTp系列中的四吡啶并卟啉钴是所探索的最有效的催化剂,它可使电池容量提高125%。对于不同系列的催化剂,配体、中心金属和取代基团对催化活性都起到一定的作用。提出了单核金属酞菁的"双活性点模型(DASM)"理论。The catalytic activity of mononuclear metal phthalocyanines to lithium/thionyl chloride battery has been studied.A series of single-core phthalocyanine complexes with different structures were designed and synthesized.The electrochemical activity of lithium/thionyl chloride battery was measured under a constant resistance using the phthalocyanines as electrocatalysts in the electrolyte.The catalytic mechanism of metal phthalocyanines is speculated according to the catalytic activity.The results show that the majority of metal phthalocyanines can increase the energy of the battery by 15%–125%.Cobalt tetrapyridinoporphyrazine is the most effective catalyst which was found currently in this study,and the energy of lithium/thionyl chloride battery with this catalyst could increase by up to 125%.For different series of catalysts,ligands,central metals and substitutional groups all play certain roles in the catalytic activity.The double active site model（DASM） theory in which the ligand and the central metal ion are possible catalytic active sites is proposed.
