We present a new method for the production of ordered 3D metal-nanowire network films using a coating of lipid inverse cubic phase as the template for electrodeposition. We have produced platinum films which show a previously unreported “single diamond” nanoarchitecture with tunable nm-scale pore and wire diameters, and lattice parameters down to below 10 nm. The nanoarchitecture gives high electrocatalytic performance and stability towards fuel cell oxidation reactions; and the production and removal of the template is facile, using mild conditions and green solvents (water, ethanol) in simple half-hour steps, representing an attractive route to high performance nanomaterials.
