Abstract
The present invention provides a novel solution or route for metal phosphide (MPx) nanomaterials from the thermal decomposition of metal bis[bis(diisopropylphosphino)amide], M[N(PPri2)2]2, and/or single-source precursors. Synthetic routes to MPx nanomaterials may be used in energy applications including batteries, semiconductors, magnets, catalyst, lasers, inks, electrocatalysts and photodiodes.
Claims12
A method of making nanomaterials comprising the steps of:
- providing a precursor, said precursor is a solution comprising a metal bis[bis(diisopropylphosphino) amide [M[N(PR2)2]x]y;
- thermally decomposing said metal bis[bis(diisopropylphosphino) amide [M[N(PR2)2]x]y precursor to form metal phosphide nanomaterials;
- wherein M is a metal;
- wherein R is a linear or branched alkyl group and substituted analogs, an aryl or substituted aryl, a silyl alkyl or silyl aryl, or mixtures thereof;
- wherein x is 0, 1, 2, 3, 4, or 5 depending on the valent state of said metal;
- and wherein x is chosen to balance the charges of said [M[N(PR2)2]x]y molecule;
- and wherein y ranges from 1 to about 5.
