It is a highly desirable but still a challenging task to find a simple, fast and straightforward method to greatly improve the electrochemical properties of a Co 3 O 4 electrode for pseudocapacitors. In this study, we demonstrate that developing an amorphous Co-phosphate (Co-Pi) shell via in situ surface derivatization on a Co 3 O 4 nanowire (NW) surface facilitates the diffusion and reaction of electrolyte ions and leads to distinctive conductivity. Because of these advantages, 1D nanostructures and the synergistic effect between Co 3 O 4 and ...
