Pseudocapacitive properties of electrodeposited porous nanowall Co3O4 film

Abstract. A porous nanowall Co3O4 film is prepared by a facile cathodic electrodeposition. The as-prepared porous nanowall Co3O4 film shows a net-like porous structure with huge porosity. The porous network is made up of free standing interconnected Co3O4 nanoflakes with a thickness of 20 nm. As cathode material for pseudocapacitors, porous nanowall Co3O4 film exhibits weaker polarization, …
