Abstract
Reagent complexes have two or more elements, formally in oxidation state zero, complexed with a hydride molecule. Complexation with the hydride molecule may be evidenced by shifts to lower binding energies, of one or more electrons in each of the two or more elements, as observed by x-ray photoelectron spectroscopy. The reagents can be useful for the synthesis of multi-element nanoparticles. Preparation of the reagents can be achieved by ball-milling a mixture that includes powders of two or more elements and a hydride molecule.
Claims17
A reagent comprising a complex having a formula:
- Q0·XΨ
- wherein Q0 comprises two or more elements, formally in oxidation state zero, wherein X is a hydride molecule, and wherein y is an integral or fractional value greater than zero;
- and wherein the two or more elements comprise at least two different element types selected from a group including:
- metals, metalloids, and non-metals.
A method for synthesizing a reagent, the method comprising:
- ball-milling a mixture that includes:
- powders of at least two elements comprising:
- a powder of a first element of a first element type;
- and
- a powder of a second element of a second element type;
- and
- a bulk preparation of a hydride molecule,
- wherein the first and second element types are selected from a group including:
- metals, metalloids, and non-metals;
- and wherein the ball-milling produces a complex having a formula:
- Q0·XΨ
- wherein Q0 is the at least two elements, formally in oxidation state zero, X is the hydride molecule, and y is an integral or fractional value greater than zero;
- and.
