Metal alloys from molecular inks

摘要

Low temperature processes for converting mixtures of metal inks into alloys. The alloys can be dealloyed by etching. A method comprising: depositing at least one precursor composition on at least one substrate to form at least one deposited structure, wherein the precursor composition comprises at least two metal complexes, including at least one first metal complex comprising at least one first metal and at least one second metal complex different from the first metal complex and comprising at least one second metal different from the first metal, treating the deposited structure so that the first metal and the second metal form elemental forms of the first metal and the second metal in a treated structure. Further, one can remove at least some of the first metal to leave a nanoporous material comprising at least the second metal. Precursor compositions can be formulated to be homogeneous compositions.

1. A composition comprising:
at least one first metal complex, wherein the first metal complex comprises a first metal and at least one first ligand and at least one second ligand, different from the first ligand, for the first metal; at least one second metal complex, which is different from the first metal complex, and comprises a second metal and at least one first ligand and at least one second ligand, different from the first ligand, for the second metal; at least one solvent, wherein for the first metal complex the metal is silver, the first ligand is an amine ligand, and the second ligand is a carboxylate ligand, and wherein for the second metal complex the metal is gold, the first ligand is a thioether ligand, and the second ligand is a carboxylate ligand.
