英文摘要： Due to the novel properties and unique structures,such as high conductivity, convenient regulation of structures, and superhigh surface area, aligned carbon nanotubes (ACNTs) exhibit promising applications in the field of electrocatalysis. However, how to further improve the electrocatalysis activities is still a big challenge to the research community. One key is to supporting appropriate catalyst on ACNTs to develop composite electrodes. Metallophthalocyanines (MPcs) have been intensively studied as one family of catalysts with high catalytic activities for various reactions. They can be functionalized with different groups and coordinated with different metal atom, which will enable MPcs with different catalytic activities and selectivities. ACNTs electrode surface modifications with MPcs can enhance electron transfer reactions, which will facilitate the coordination electrocatalysis activities of ACNTs and MPcs and largely improve the electrocatalysis activities of ACNT. This research plan developed a series of methods for the preparation of ACNTs with different structures, and MPcs with various substituents on the conjugated ring and different metal atom in the center of the ring. Several routes were also designed for the composite of ACNTs and MPcs. All the influence factor on the electrocatalysis activiti
