This invention discloses a coordination polymer-coated catalytic material derived from twisted polypyrrole nanotubes, its preparation method, and its applications. First, using a chiral surfactant as a template, a helical polymer structure is formed by inducing polymer monomers to act as the core. Then, a transition metal source is introduced to further assemble a helical support. Next, an organic ligand is used for coordination coating to form a shell. Finally, after pyrolysis under an inert gas, a dense twisted carbon layer is formed at the core-shell interface, yielding the coordination polymer-coated catalytic material derived from twisted polypyrrole nanotubes. The introduction of the helical core in this catalytic material not only helps form a twisted carbon interface but also helps induce a uniform distribution of transition metal active sites. The preparation method of this invention is convenient, and the obtained catalytic material exhibits good oxygen reduction / evolution bifunctional catalytic activity, stability, and applicability to flexible zinc-air batteries.
