Mesoporous gold sponge may be prepared by the removal of aluminium from AuAl2 by an alkaline leach. The
resulting material has nanoscale pores and channels, with a high specific surface area that can be exploited in
electrochemical applications. For example, the material could conceivably serve as the basis of a more sensitive
capacitive sensor or biosensor, as an electrode material for a high efficiency ultracapacitor, as the semi-transparent
current collector in a dye sensitised photovoltaic cell, or as the lithium-storage electrode in a lithium ion cell. The
properties of the sponge may be controlled by varying its density, pore size, and pore size distribution, factors
which are in turn controlled by the microstructure of the precursor compound and the conditions of deposition.
