【 摘 要 】

The high dispersity and conductivity of materials are of great significance in the field of energy conversion and storage. In this work, a highly dispersed ZIF-67 anchored onto polypyrrole nanotubes precursor with good crystalline is prepared via self-assembly through coordination between cobalt cation and 2-methylimidazole assisted with deprotonating agent of triethylamine. The as-synthesized precursor displays a dense coating layer wrapping high aspect ratio polypyrrole nanotubes as clearly observed by scanning electron microscope. This work provides a rational route in construction of hierarchical composites with high conductivity and outstanding catalytic property applied in electrocatalysis and energy storage device.
