Mesoporous nickel/nickel oxide electrodes for high power applications
Mesoporous nickel/nickel oxide electrodes for high power applications
Mesoporous nickel electrodes have been electrodeposited by reduction of a nickel (11) solution dissolved within the aqueous domains of the hexagonal (HI) lyotropic liquid crystalline phases of Brij((R)) 56 non-ionic surfactant. The nanostructured films consist of well ordered, periodic arrays of channels disposed on a hexagonal lattice with nanometer-sized dimensions. Cyclic voltammetry has shown these materials to have high surface areas (typically surface area enhancements of 100 times over non-templated electrodes) and a pore structure that allows extremely rapid diffusion of species to active sites within the structure. These characteristics suggest application as a low cost current collector and use in high power devices.

Abstract
Mesoporous nickel electrodes have been electrodeposited by reduction of a nickel (11) solution dissolved within the aqueous domains of the hexagonal (HI) lyotropic liquid crystalline phases of Brij((R)) 56 non-ionic surfactant. The nanostructured films consist of well ordered, periodic arrays of channels disposed on a hexagonal lattice with nanometer-sized dimensions. Cyclic voltammetry has shown these materials to have high surface areas (typically surface area enhancements of 100 times over non-templated electrodes) and a pore structure that allows extremely rapid diffusion of species to active sites within the structure. These characteristics suggest application as a low cost current collector and use in high power devices.
