Electrochemical dealloying has proven to be an efficient way of fabricating nanoporous gold, the morphology of which can be tailored by controlling factors such as the etching time, temperature of electrolyte, composition of the alloy, pre and /or post heat treatment and voltage to suit applications such as fuel cell electrodes and sensors. This work aims at studying the effect of such factors as the electrolyte concentration on the morphology of the emerging material. A model relating the processing parameters and pore size is established by statistical approaches using the Design Expert 7.1...
