Abstract
A method for the fabrication of a mesoporous metal electrode in a non-liquid crystalline phase was tested. Specifically, there was tested the efficacy of the method for the fabrication of a mesoporous metal electrode which comprises forming the mesoporous metal electrode on a substrate by chemical or electrochemical reduction of a mixture comprising a solvent, a structure-directing agent, and a source of a metal, characterized in that the mixture is maintained in a non-liquid crystal phase. Furthermore, the usefulness of the mesoporous metal electrode thus prepared from the non-liquid crystalline phase was also tested. The mesoporous metal electrode prepared from the non-liquid crystalline phase had a large surface area, and a roughness factor thereof was controlled by charges passed during electroplating. The method made it possible to fabricate the mesoporous metal electrode in the non-liquid crystalline phase, even more flexible than a liquid crystalline phase. The mesoporous metal electrode prepared by the method had randomly distributed mesopores on the surface thereof and retained a large roughness factor. The method was found to be a good alternative to the conventional fabr…
