Hollow octahedrons of polyaniline (PANI) were prepared using Cu 2 O as a template in the presence of H 3 PO 4 and (NH 4 ) 2 S 2 O 8 as a dopant and an oxidant, respectively (see Figure). The Cu 2 O template can be used to prepare different morphologies of PANI (e.g., hollow octahedrons and spheres). Compared with other conventional templates, the Cu 2 O template is unique (in terms of both shape and quality) and omits the need for template‐removal treatment.
